Firefox Community Forum

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?

(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 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.

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, I just updated to Firefox version 146, and now the bookmarks and history in the sidebar are no longer visible because the background is yellow-green and the text is white...so, invisible!

I hope you will fix this quickly with a new update, as it's a real problem.

Thank you in advance. Sincerely,

SEVERAL SITES THAT I USE ARE NOT LOADING CORRECTLY WITH MY CURRENT AD BLOCKER. WHEN I DISABLE THE AD BLOCKER THE SITES LOAD NORMALLY. I AM NOW USING A DIFFERENT BROWSER UNTIL A SOLUTION IS FOUND.

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.

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?

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.

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.

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

Mozilla will not let me sign into my Amazon account without using a passkey. I have never established a passkey and I do not wish to use my phone to sign in and without using one of those two options, my computer is completely locked and I have to shut it down and reboot or sign out of Microsoft in order to regain service. I have deleted Firefox from my phone...I have deleted the Amazon app from my phone, and I unsynched everything before I did so. I have errased all of my cookies and cleared the cash. I use an Apple phone which is equipped with an excellent browser, and unless I can find some work around for this I am going to delete Firefox from my PC as well.

These are technically two separate issues, but both pertain to functionality of the mouse and keyboard. Whenever I right click to bring up the menu, the options (despite being functional) do not appear in the menu proper. Instead there are just empty buttons. In addition, certain hotkeys aren't working at all. Ctrl+C and Ctrl+V to copy paste are doing fine, but Ctrl-T and Ctrl-W to open and close tabs respectively do nothing. Neither of these issues were happening yesterday.

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.

Whenever i search something on google, firefox desktop (all fine on android) is failing to display the ai(gemini) answer no matter what questions i ask.

Same happens in the "AI Mode" option that is available in google's recent update.

And, I,m logged in.

This started since a week, everything was working fine before that.

Adding the images below.

macOS 15.6.1 Firefox 142.0.1

When I try to login to Facebook I can't and a screen appears with

"Sorry! Something went wrong :(

This happens even in Troubleshooting Mode …

Exactly the same issue with DuckDuckGo browser but no difficulties with Safari where I can login to Facebook as usual …

I have read all your tutorials. I was unable to have an important televisit with my doctor yesterday because nothing I tried worked. I am unable to use webcam for other sites until I resolve this problem. Previously I had no problem with my webcam but recently had to get new pc with windows 11 & needs to configure my pc to address this issue. I have another appt scheduled with another doctor & need to fix this problem asap Thanks
