I just updated to the latest version of Firefox, and all of a sudden I have a new icon, Extensions, that looks like a puzzle piece, I cant seem to be able to remove it....at all.

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

I made a small CSS customization to my tabs in FF 115 ESR on Windows 7, so they would be flat on the bottom and rounded on the top, looking a bit more like tabs instead of buttons.

Looked ok in FF 115 ESR.

However, in FF 125, half the tabs are now cut off, including their text (see attached images).

Also the tabs background is darker in FF 115 ESR, providing more contrast between the tabs and the tab bar. In FF 125, it's almost all white and I can hardly distinguish between the tabs and the tab bar.

Why is there such a big difference in appearance between FF 115 ESR on Windows 7, and FF 125 on Windows 10?

Here is the code I used...

/* ------------------ RESIZE TAB BAR ----------------------------- */ \#TabsToolbar { height: 27px !important; margin-top: -1px !important; margin-bottom: 0px !important; } \#tabbrowser-tabs { height:25px!important; min-height:25px!important; }

.tab-background-start[selected=true]::after, .tab-background-start[selected=true]::before, .tab-background-start, .tab-background-end, .tab-background-end[selected=true]::after, .tab-background-end[selected=true]::before {

 min-height:25px!important;

.tabbrowser-tab {
 max-height: 25px !important;
 border-color: #8f939e;

 max-height: 25px !important;
 border-color: #8f939e;

} /* ------------------ TAB HEIGHT END ----------------------------- */

I inserted backslashes at the beginning of the first 2 lines of code above to preserve the hashtag sign (otherwise it displays an index number before those lines), please ignore the backslashes.

I would like my customizations in Firefox 125 to look like the ones I made in 115 ESR.

Is it possible?

Thanks!

How do I get the + sign back on my tabs? After latest update I can only close tabs instead of opening new tab, and I am talking about after opening several tabs. When I have seven tab open, I have to do ctrl+t to open new tab instead of just clicking on the + sign that use to be at end of tabs. Yes, I do use custom settings. This happened before but I was able to fix by going to tabs under about:config, but it seems the setting is no longer there.

Yahoo isn't loading at all for me, more specifically guce.yahoo.com. I have managed to get into the login.yahoo.com page and log in but after the log in process it goes to the first page again and gives me the same "The connection has timed out". I just installed the browser and this might make me not use it ngl. I have tried both clearing cookies and troubleshooting mode.

I have various shortcuts saved on the shortcut page comes up after logging in. Its set to 2 rows.. I use it every day. Used it this morning and working perfectly. Been out and when I came back the page is totally blank. I've tried sytem restore to 5th October but makes no difference. I use Windows 10 and read that Firefox are continuing to support Windows 10 I'm visually impaired and use a desktop PC with a large screen. I'm not PC techically knowledgeable. How do I restore my shortcuts or how do I re create them?

I'm using Firefox 129.01 (64-bit), trying to log in to my Tufts Health Plan account, and get a security warning (screen shot attached). Customer Service at Tufts Health Plan tells me that I should use Chrome.

Should I ignore the Warning and proceed?

let's keep it as brief as possible.. i have no idea what the hell the degraders of cloudflare are doing, for the past YEARS all sites that required cloudflare worked just fine, and now i lost access to multiple sites on firefox because of the cursed "are you human: captcha loop" i'm looking for extensions, i'm seeking github codes that i don't even know how to execute. the loop keeps demanding me to change the browser to a chromium.. isn't this supposed to be treated as a targeted cyber crime? from google against mozilla? how do i fix the captcha endless loop?

Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?

When I swipe to the left, Firefox navigates Back & when I swipe to the right, Firefox navigates Forwards. It is VERY ANNOYING!!!! It's really easy to do this accidentally while scrolling around a large web page. When you go back, it deletes all data that was filled out on the web form causing DOUBLE the work. How do I turn it off please? Win 10, FF 142.0.1 64-Bit

Roughly every 2 weeks I backup important files to a external hard drive.

One of the things I always backup is my Firefox profile. I have been doing this for years without any problems.

I 7zip my profile and copy it to the hard drive.

I tried to do this yesterday (July 25 2025), and was getting access denied messages for files in the profile. So I tried to simply copy the profile. Same thing access denied.

I cleared the history, used wise disk cleaner, rebooted my machine and tried again. Same thing access denied when trying to backup or copy the profile.

I am assuming that this is happening since 141 because I updated Firefox since the last time I backed up my profile, and never had a problem previously.

Could anyone have an idea what the problem is? Thank you for your time.

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

Hello everyone! I want to see every visit on a site by date and time. But in library of history it offers me to see only last visit by date(for example if i visited a site for example x.com 200 times - i want to see every date and time of every of these 200 visits, but not only recent). How to do it?

One quality of life thing I really miss after switching from Chrome is the option to "Goto ip" when you highlight and right click on a local ip address.

I do a lot or networking and am going to local ip addresses all the time (ie 192.168.1.1 or 10.0.20.15). When I highlight an address in the local ranges in Chrome it gives the "Goto" option, but Firefox always offers "Search Google for"

I really miss this option and unfortunately all my searching has not yield a solution since search engines cant quite make sense of my requests.

Hopefully someone here can nail something down.

Thanks!

I just started having an issue while watching Live Streams on Youtube with FireFox. I'll load the live stream and it will run for about a minute then it will switch to the streamers previous recorded stream. I opened Youtube on my iPad and on Edge browser and the Live stream keeps playing the live stream but on FireFox it only lets it run for about a minute before flipping the playback to the previous recorded video of that streamer. I tried clearing my cache for Youtube and I have no extensions running. I have Youtube Premium and run no adblockers. I have also tried safe mode but the problem persists.

Any idea what could be happening?

Recently, after the newest Windows 11 update, Twitch hasn't been loading correctly, the tab looks as if it finished loading, but the page gets stuck in endless loading, no other site has this problem, and it happens even opening links to Twitch channels directly. I've added and screenshot of the problem.

I'd love some help or at least know if this is a problem on Twitches end or not. Thanks.
