Internet Browsers: What are YOU using? (And why?) (1 Viewer)

[Mike Frezon]

I've got a question (hopefully super easy) for you smart PC guys who have helped me out so often.

I use Firefox both at work and at home.

At work I'm using the latest FF on Windows 7. At home, the latest FF on Win10.

But at work when I hover my cursor over the buttons at the top of HTF pages ("Tools," for example), the dropdown menus automatically appear.

At home, I have to actually click the button to make the drop-down menus appear.

Is there some really stupid setting (that I can't find) that would enable my home laptop/Win10/FF combo to drop the drop-down menu with the cursor hovering?

I truly wish I could tell you what's going on Mike. However I see the same behavior on the 4 systems I use and have yet to find rhyme or reason. It doesn't appear to be the version of FF. At one point I thought it might be uMatrix and something I'd set accidentally and checked those settings. Nope. A few days later it started working with no action on my part. It's possible I may have restarted the browser at that point but couldn't tell you. On my home systems I run the browser all the time with very few full restarts of either Windows or the browser. At work I restart every day. There have been times one of my work systems has been affected and others it's been at home.

FWIW I'm running Windows 10 Home on my home laptop with FF v62.0.3 and haven't had that issue for a few weeks. The desktop is Windows 10 Pro with a much older version of FF (on purpose) but I rarely access the site on that system. At work I'm running Windows 10 Education with FF 65 (? - not exactly sure but it's the next to latest version and the hassle I had getting tabs and everything back like I wanted after that update has kept me on lower versions everywhere else for now) and don't have the issue there either on one system and Windows 7 Pro with FF 63 (? - again not exactly sure but it's a higher than at home but not as high as my main WIn10 system).

So... all that said... maybe close FF and reopen it will do the trick.

 

[Mike Frezon]

Nah. This is a fairly permanent situation. It's been this way for months. Both machines have been restarted, rebooted, had the browser updated, etc. several times.

Except for the operating system (Win7 vs. Win 10) both machines have the latest FF installed. Both have the same code installed to get the tabs moved to the desired location. But on my work machine (with Win7) I hover over a drop-down button and the drop-down automatically drops. But, at home, I have to actually click the button to get the menu to appear.

I can't find settings for that functionality anywhere.

Thanks, Howie.

Can any Firefox users explain the deal regarding these super annoying "Critical Update" messages that I seem to be getting with annoyingly high frequency?:

Below is the prompt I got upon trying to reenter my sign in email address:

From what I've read online, this could be malware, but if this is the case, how in the F___ is it managing to embed itself within the actual FF browser?

I probably should clarify that each time this "critical Firefox update" message occurs, it involves downloading the EXACT SAME Firefox Installer file, and the size of the file is ALWAYS 314 kb! It also appears to be an update loop, in that I've lost whatever "new" settings I had in the "previous" update, and that I have to initiate the "current" update just to restore what I already had before! SHEESH!!!!

In the past 2 weeks my Microsoft edge browser would close and then a minute reappear again. Even the Edge icon at the bottom of the screen would disappear too and it did this once or twice a day. Changed over to Chrome and much faster loading and no issues so far.

I'd either update from within FF itself (Help - About FF - Update) or download the latest installer and install over the current installation.

I've just discovered a handy feature of Edge. Up to the left of the star icon for saving a bookmark, there's an open-book icon. Click it and the page displayed may be viewed in some kind of "book mode" which is much easier to read. The open book icon only gets active for some but not all articles at a web page.

Do other browsers have a similar book mode?

Safari ..I guess Im using it because it is what came on my I mac ..

Definitely. Always go to the original official download page for any browser/software updates. (Also check hashes on such downloaded executable files, if available).

Pocket (suggestion: disable / set to 'false')
extensions.pocket.enabled

The easiest way around the "built-in" addons like pocket, etc ..., was to just delete the corresponding *.xpi outright from C:/Program Files/Mozilla Firefox/browser/features

Some annoying built-in addon *.xpi are in the profiles directory, usually in something like C:/Users/*yourloginname*/AppData/Roaming/Mozilla/Firefox/Profiles/**yourprofile**/features

Mike,

I may have an easier way than the manual stuff. I discovered I can upload files so I've attached a userChrome.zip file. Download and unzip it and you'll have the userChrome.css file for "tabs on bottom" to drop in the Chrome folder in your user profile folder. It only contains the tabs-on-bottom css code and not the code that changes the URL bar.

For fun, I tried this Howie css file on recent versions of Firefox. It seems to largely do nothing now.

It appears to be completely absent on FF 69 Nightly. (ie. Does absolutely nothing).

It doesn't do much of anything on the current stable FF 67 and beta FF 68 builds, other than changing the color of the tabs horrizontal bar.

I went back to an old copy of FF 56 which I haven't deleted yet and tried running it. It turns out it still works as "tabs on bottom" on FF 56.

For this "tabs on bottom" stuff to possibly work (in principle) on FF 69 Nightly, I had to change in about:config

toolkit.legacyUserProfileCustomizations.stylesheets

to true.

For this "tabs on bottom" stuff to possibly work (in principle) on FF 69 Nightly, I had to change in about:config

toolkit.legacyUserProfileCustomizations.stylesheets

to true.

In addition to the above ^ modification in about:config, I finally figured out how to get "tabs on bottom" to work on the FF 69 Nightly builds.

I had to cut and paste the relevant css code from the latest versions of :

https://github.com/Aris-t2/CustomCS...ic/css/tabs/tabs_below_navigation_toolbar.css

https://github.com/Aris-t2/CustomCS...s/tabs/tabs_below_navigation_toolbar_fx65.css

https://github.com/Aris-t2/CustomCS...s/tabs/tabs_below_navigation_toolbar_fx68.css

into one big userchrome.css file.


I didn't include the lines

@import "./tabs_below_navigation_toolbar.css"; from tabs_below_navigation_toolbar_fx65.css

@import "./tabs_below_navigation_toolbar_fx65.css"; from tabs_below_navigation_toolbar_fx68.css

 

[jcroy]

^You can do colors too. Just more CSS to add to the userChrome.css file.

https://github.com/Aris-t2/CustomCS...c/css/tabs/custom_colors_for_squared_tabs.css

https://github.com/Aris-t2/CustomCS...ustom_colors_for_squared_tabs_australized.css

I've not played with either of those so don't know just what they'll do or how to modify them to make colors do what you want.

It appears these ^ css files are now gone.


Though from reading through Howie's second userchrome.css upload in this thread,

I've uploaded my current userChrome.css file (as a zip). It has tabs operating the way I like (they'll get ridiculously small and do not scroll - ever), expand properly to fill the tab area when some are closed, as you close tabs the ones to the right pull left and the "X" to close them are under your cursor, have slightly rounded (some call them square) edges, are below the URL bar, and a few other tweaks. They are "plain Jane" grey as I couldn't care less about colors on tabs. The current tab will be FF orange.

An earlier post of mine has links to the site where I got my mods and has information about putting color on the tabs.

I'm guessing the content in those two dead links are now in the files:

https://github.com/Aris-t2/CustomCSSforFx/blob/master/classic/css/tabs/classic_squared_tabs.css

https://github.com/Aris-t2/CustomCS...css/tabs/classic_squared_tabs_australized.css

https://github.com/Aris-t2/CustomCS...s/tabs/classic_squared_tabs_fully_squared.css


So I copied the css code from the latest update of classic_squared_tabs.css into my own userchrome.css file from my previous post. From reading the follow up posts to the referenced Howie's posts, I'm guessing what I'm currently seeing on FF 69 Nightly is possibly replicating the function described by Howie and others.

 

[jcroy]

Hmmmm .....

I tried several of Howie's custom color settings css code (with red, purple, etc ....) in my own userchrome.css file.

So far I can't seem to get any colors in the tab bars, other than white and greyscale.

I'll have to take look at a custom_colors_for_squared_tabs.css from an older version of CustomCSSforFx to see what they did.

It's *very* messy... likely has duplicate sections as I've just not looked at it closely.

It provides the ever shrinking tabs (non-scrolling) I like but has rather plain tab colors of grey with FF orange for the current one. I'm OK with that as the main things - tabs on bottom and non-scrolling "squarish" tabs are present. I've not gone over it to see just what's absolutely needed since it does what I need/want.

Thanks for the update BobO'Link.

For most of my casual web browsing, I'm on FF Nightly. I can deal with stupid alpha behavior, frequent crashes, etc ... when reading dumb stuff and watching youtube videos. Hopefully the dozen+ crash dumps I send in every day will help in debugging and a more stable browser.

Most of my tinkering in about:config and userchrome.css are done with FF Nightly.

On the other hand, I use the current stable FF 67.0.2 for serious stuff. (For example such as: online shopping, work related stuff, etc ....).

You're welcome.

I use FF Portable and *always* make a backup of the system (usually copying the entire folder but sometimes just the app subfolder) before allowing an update to install. If the update breaks the css file I roll back and look for fixes before I'll use it everyday. I don't bother with the nightly updates. If they're not going to listen to my suggestions about what they break in the GUI then I'm not helping debug their crap.

**Warning - RANT follows**

The GUI stuff is usually forced through arrogance - the "no one uses that" excuses when it's actually them wanting to force the way they think things should be and won't listen to outside opinion/suggestion. I've found most GUI "designers" are the same - a bunch of arrogant dolts who wouldn't know a good design if it slapped them in the face. Stuff along the lines of "Look! Isn't that pretty!?!" totally ignoring that functionality was thrown out the window in favor of a "pretty face." My workday is 25% less productive because of GUI redesigns (not just FF) that substituted form over functionality. And the form isn't that good either.

In practice, I've found that the only files I need to restore + reinstall Firefox from scratch again (after complete corruption or beyond repair), are:

- prefs.js
- booksmarks (if one uses any bookmarks)
- userchrome.css (if applicable)

Whenever I do a semi-regular backup of my files, I'll make a copy of my customized prefs.js and bookmarks files.

I run uMatrix and AdBlockPlus. Both of those have their own stuff to backup properly. Because of those and cookies which contain data I want to preserve I've found it's easier to just backup the entire structure. Since it's portable it's as easy as stopping FF, copying the portable folder, start it up and update. If it breaks - delete the original folder and rename the backup (or copy the copy and rename that - depends on my mood).
