Firefox Community Forum

Using Firefox, my gmail inbox is my home page - and has been for several years. As of yesterday, the page opens but the page is blank. I am not aware of any changes that I have made.

I do not have this problem using chrome on the same device or firefox on other devices.

Probably something simple, but I have no idea what.

Thank you

I have the box ticked in Settings for previous tabs to be installed on Startup but it isn't happening although it used to. I was trying to get rid of caches (what are they?) and must have done something.

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 !

For first time received email from breach-alerts@mozilla.com. Title is: Your monthly Mozilla Monitor report. Is this a scam? Other people have asked this question and Mozilla Firefox company has not made any attempt to answer these serious questions. If I do not hear back from Mozilla Firefox within a week I might remove Mozilla Firefox and use another company.

I'm trying to sync my tab groups across my desktop/laptop. I have sync enabled through the settings and I've checked every box, but I don't seem to see an option for syncing tab groups specifically. It syncs all of my bookmarks and active tabs, but the groups seem to be unique to each device. Is this feature available? I might be looking in the wrong spot so if anyone has any insight that would be great! Cheers

I believe there was a button to send a url link by email on Firefox. I tried to find that button everywhere, but I still can't find it and it didn't even get to an answer for this by asking questions on Mozilla website. Could you kindly guide me where to find that button?

Thank you in advance.

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.

Firefox mozilla recently updated, now the bookmark side bar has made the fonts dark on a dark background, now unreadable. How do I change the fonts back to white on a dark background?

Can anyone tell me, please, how long I should be able to keep accessing Firefox on a Windows 10 tablet after Microsoft withdraws support for Windows 10 later this year? I seem to remember being able to access the internet on an old laptop as a 'test' a year or two after I'd stopped using it after Microsoft stopped supporting whatever version of Windows was on it, but I can't remember whether it was via Firefox or Internet Explorer or some other Microsoft browser. If Firefox will still 'work' will Microsoft withdrawing support for Windows 10 have any effect on how well it 'works', and/or how secure etc it will be? I am going to try to install some sort of Linux on the tablet (well) before Microsoft abandons Windows, but if it turns out I can't install Linux, I'm hoping I should at least be able to access the internet via Firefox. Thanks to anyone who can help. (ps I'm not sure whether this is the right place to post this question, it's just that performance and connectivity seemed to me [in my ignorance] to be most appropriate!)

I'm running version 118.02.2 (64-bit) of Firefox on Windows 12. I *always* have the 'Open previous windows and tabs' checked. Starting yesterday, Firefox opens with nothing other than a blank page. Luckily for me, this has happened in the past and I have a Bookmarks Menu folder with my default tabs saved. Even so, it's still frustrating.

First, I tried to install via the web download from mozilla.org. That led to the wont-start-up problem. Then I reinstalled and reset my computer, and had the same problem. Then I uninstalled and reinstalled via the microsoft store, and that worked fine, and got my browser set up. That was all yesterday. Today, I tried to open firefox, and it once again wouldn't start. I'm pretty sure I shut down my computer overnight between yesterday and today. So, I uninstalled and reinstalled via the microsoft store. Here's the *really* weird part: today, when trying to launch firefox, windows will instead open a different program, seemingly at random. When launching firefox, it has instead launched:

• Audacity
• Some AMD software thing
• Calculator
• Microsoft office

It won't open even if I try to open it in troubleshoot mode. I tried to find the crash logs file in my system that some support article recommended I find, and windows couldn't find that file. No error message or dialogue box appears when firefox crashes on start. I'm running windows 11 on an amd gpu and cpu. Help me not use google anymore!

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.

How do I move an addon from the TOOLBAR into the PUZZLE PIECE list? I can get them OUT onto the Toolbar.

Also, the Customize Toolbar / overflow menu won't accept anything, the addon just pops back out when dragged from the Toolbar.
