I just updated Firefox and the bookmarks on the left become all black. Black font on black background. Unreadable. Before that, the font was white.

How do I change that ?

Thanks !

With a catastrophe with my System I almost reinstall all Software including Firefox than I found the address bar changed a lot in the latest version.

For the old version when I type words, press the down key to switch your engine below, but the new version they disappear! Even for alt+↑ or alt + ↓ are disabled now, may it be too radical?

I really like the engines below in the old version, thus, a option for let the engines shows below may pretty helpful

Reference: Firefox Desktop 139.0.1. See the attached image. What does the overlaid blue (cable with plug?) icon mean on top of my Grid Overlay bookmarklet? The overlay appeared after the update to v139.0.1 (desktop) on Arch Linux. And only on top of my bookmarklet. In case it's relevant. The bookmarklet consists of JS that injects some HTML in the rendered webpage and then beckons my grid overlay. Self developed to overlay my own web layouts.

I took a look today and I had 237 MB in cookies! This was after clearing the cache of all files. I've only had this (new) machine a couple months.

Short version: Sites have "cookies" from 200kb to as much as 34MB! For many of the sites over 3MB I have no account and have visited them only briefly.

To be clear, I don't care about the space being used. It's trivial. But what the heck is FFox storing and calling it "cookies"? Last I checked, a site was still limited to 4K size cookies and perhaps 50 per domain. So how are we getting to MB+ sized "cookies" per site? Again, the cache was cleared, so what's left aside from trivial cookie files of <4KB?

I watch Rakuten Viki, and suddenly a recapcha box is popping up on the bottom right, blocking the full screen button.... so annoying,,,, how can i get rid of it/ THANKS

Whenever I search something and there is a youtube video included in the search results, all links direct to that video. In the example image it show me hovering over a website link and in the bottom left hand corner it instead tries to open a youtube link at the bottom of the page.

I am having trouble signing into my account ******@gmail.com. I no longer have an authenticator app account and I used all of my backup codes. I do have a recovery key though. I hope this helps in recovering access to my account.

Today I opened Mozilla at my laptop. It malfunctioned (videos froze, pages did not fully download), so I closed the window and after a couple of seconds I reopened it. My previous session was gone. I read your articles regarding this issue, did what was described there, but nothing has changes. I lost everything! Job videos, hobby pages - everything! A couple of pages can be restored via history, but that's it! I didn't do anything special before closing the window!

I usually watch YouTube with Enhanced Tracking Protection turned on, Private Browsing turned on, and cookies turned on without logging in, but I have never had any problems. I can no longer open YouTube pages at all unless cookies are turned on. I will ask Google to improve this, but could Mozilla also investigate the cause? Thank you in advance.

Firefox screws up showing .pdfs. The first view is fine but scrolling seems to overprint the first view without erasing it, if that makes sense, sorta like a double exposure. I can't get a screen cap either, which might just mean it's not a firefox issue at all, but I can view and screen cap .pdfs from any other application. I'm running Debian 12 up to date. When I need to view a .pdf I use Chromium, but I do prefer Firefox.

Hello everybody, Is there any way to revert unloaded tabs favicon revert back to slightly pale colored version like in 137 instead of non-colored b&w favicons.

Hello:

When I signed into my computer this morning, a pop-up asked me if I wanted Firefox to update. I let it do that, and then a pop-up came up letting choose among some photos and art for a desktop background. It even let me upload a photo of mine. I chose one of yours, now I can't change to any other photo I have on my computer. Please help.

Thank you,

Cynthia M.

I rebooted and launched FF, I was asked if I wanted to Refresh. Naturally I declined because I'm not an idiot. Now all my addons and passwords are gone. I would love to have them back since I never asked for them to be deleted. I don't have an "Old Firefox Data" or whatever folder on my desktop, would have been cool for them to leave that there when they clobbered years of data and customization because Firefox thinks they should have more control over my PC than I do, but they didn't. Is there any way to get these back?

Looking for a way to configure the "Share the screen" permission present in permissions for individual sites via GPO. I am aware of this doc but I can't find anything for setting this permission. Specifically, to block it for all sites with an explicit allow list.

The "Preferences" option won't suffice as permissions are stored in permissions.sqllite and are not part of the about:config preferences. The "Permissions" grouping lacks... the majority of the possible site permissions as well.

Google provides a different key to differentiate installed copies of Google Chrome (standard or "Google Chrome for Work") in this file:

"/Applications/Google Chrome.app/Contents/Info.plist"

Google Chrome:
<key>KSBrandID</key>
<string>GGRM</string>

Google Chrome for Work:
<key>KSBrandID</key>
<string>GGRO</string>

Is there such an identifier on Firefox vs Firefox ESR?

Thanks, Don

It has pulled in a list of mostly obsolete accounts and passwords which are listed when I select "passwords" I did not ask firefox to do this. why has it done this. what else may it have done that I don't know about
