When is do a search in Firefox I noticed that it now searches with "rini.drorinat.com" is this still Firefox or have I been violated? I tried to look up this site but no success, could you help with this asap please?

Hello all:

Just downloaded version 140 and ran into an immediate "visual/appearance" problem with regard to the background color(s) of the sidebar bookmarks view. Many themes now have totally dark sidebar colors and not readable (see screenshot image upload with this posting). I always have my bookmarks (almost 1200 of them) displayed in my sidebar, and this is the first time an issue like this has arisen with a Firefox update.

To remedy this scenario, I must use very light colored themes that have a white background when you bring up the sidebar bookmarks. If not, everything is totally dark and unreadable.

Any ideas or help on this one?

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

Hello,

Since update 140.0, the side panel is dark (no problem), but the text is black instead of white!!! Which makes reading black on dark is very complicated... Could you fix this problem with a new update? Thank you so much in advance.

Hi everyone

I used Refresh Firefox option and it created "Old Firefox Data" folder on my desktop.

Awesome stuff. Sadly I cant get rid of it, here is why:

1. At first it said that the folder is used by another program and I cant delete it because of that. Cool, I decided to uninstall Firefox and make a clean install, so I have space to delete the folder too.

2. Long story short, it didnt work. I removed Firefox and tried to delete that folder, but wait for it, yeah I cant because I need permission from MYSELF. Awesome stuff.

3. I decided to use safe mode, so I used run command to run msconfig and I changed it to boot in to safe mode. But wait for it! YES! Its bugged and I cant login in safe mode, because pin is useless and it doesnt give me option to use password, so after hour of various things I got back to my normal mode via CMD commands. THANK YOU MICROSOFT.

4. So now Im stuck with the lovely "Old Firefox Data" folder, which cant be removed normally, neither in safe mode and wait for it! NEITHER WITH ADMIN CMD, not even the takeown /f "Old Firefox Data" /r command. THANK YOU MOZILLA!

So is there someone knowledgeable enough to help me to get rid of that folder pretty please? Like really a lot please.

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

(If any relevance, I'm on Macos 12 Monterey) 'Installation and updates' seemed the nearest topic due to the 'update' part of it, since this seems to only have been happening since this version, or I have simply not noticed due to not having needed to know. But if you look at my two screenshots, you will see the issue. There simply is no About Firefox on my firefox. Neither directly listed on the menu, nor as part of the 'help' sub menu.

Is there, for the sake of learning, a simple fix, so that I donlt have to uninstall/re-install? or an 'about config' type fix? Screenshot 1 shows the menu Screenshot 2 shows help sub-menu As you can see, absolutely no About Firefox

And, only potential issue may be, as you'll see from the share data upload is that I've a lot of tabs open, as I've got a lot to get through toniught, and tomorrow. So, maybe, t=though doubtfully, it is because it isn't handling the tabs and this caused a menu entry to be missing? Surely not likely.

Hi there! The New Tab page looks great with white text, but Firefox 140.0.4 thinks my wallpaper is white, so text should be dark. I can change the body class to "activity-stream darkWallpaper" using the inspector and it works fine, but how make this change permanently?

I've been using Firefox since forever but over the last couple of months, the auto translate subtitles (to English) hasn't been working when watching Youtube videos. There's a thread on the Youtube support site with nearly 40,000 posts of people with the same issue and tonight I was trying to watch a video where the hosts talk in Italian, so I use auto translate to English subtitles but no subtitles appear. It will show Italian language subtitles.

I've gone back through this Youtube channel's history trying videos I've previously watched from months/years ago when auto translate used to work but even they're not working now.

I decided to try the video in Edge browser and to my surprise the auto translate to English worked there. They also work in Chrome.

So what could be causing this issue on Firefox, which started about August time?

This is quite bizarre as I assumed all the processing/translation was done by Google/Youtube so in what way can Firefox be part of this issue?

To be clear, subtitles in the (foreign) language the people are speaking, works. Subtitles translated from that language to English (or other languages) has stopped working. Subtitles translated from that language to English IS working on Edge and Chrome browser.

Why doesn't Firefox recognize my correct location? It gives me the weather for Chicago, IL on my homepage. I don't live in IL. MS Windows and Edge have my correct location, so why doesn't Firefox?

I have tried to change weather location on my Firefox homepage by putting in the correct town and state, then hitting the search icon but nothing happens, although once I was redirected to the AcuWeather site.

This is not that big a deal as I can get my weather on my Samsung phone, but it is puzzling.

Thanks for your time--Maureen

I think this might be more of a Google issue, but it happens when using Firefox so I'll post it here. As of Jun 25, 2025, I have noticed dark black boxes appearing around my Google search results. I normally use a dark theme in Google, but the color is a muted grey/black. Today, however, dark black boxes have begun appearing around my search result. I really dislike the appearance as it is quite jarring. Interestingly enough, this issue only happens when signed into a Google account. Some Reddit users have reported having the same issue even in other browsers when using Google search. It seems to be something that Google has done on thier end but I was wondering if there was a potential workaround in the meantime.

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

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 updated firefox through apt, and since then, have not been able to log into twitch I am on ubuntu 24

apt list --installed | grep firefox firefox/mozilla,now 144.0.2~build1 amd64 [installed]

Attempting to log in returns the generic "Your browser is not currently supported"

My desktop (Windows 10) Firefox just updated to 145.0.1 and the right-click menu is defective. It has a bunch of blank lines, the only options listed are search DuckDuckGo, translate, and use AI. This ruins my browsing experience, since I can no longer open links in new tabs which is my favorite way of looking at newspaper home pages.
