You say to go to the download page and my version of Windows will be detected & you'll give me the correct version. However, IE 8 in Windows 7 won't go to your download page. So, I need to download from another computer and copy the file to the Windows 7 computer. This doesn't work when you detect that the computer doing the download is a newer computer. How do I tell your system to give me the Windows 7 installer?

I have followed suggested links in ever variable circles to no avail... innumerable deletes, restarts, reinstalls etc, etc.... but still have NO ACCESS to my Bookmarks toolbar! I've worked way too long over such & would gladly forget my history... but remain unable to access the Bookmarks toolbar

Hi,

I’ve recently noticed that after a Firefox update, the browser has become very slow and unresponsive whenever I open multiple tabs, around 5–10. Before this update, I could open many tabs without any noticeable lag.

Now, new tabs take a long time to load, scrolling within open tabs feels choppy, and sometimes Firefox freezes for a few seconds before responding again.

I’ve already tried restarting Firefox, disabling extensions one by one, and clearing the cache, but none of these steps have improved the performance. I’m using Windows 10 and the latest version of Firefox.

Could anyone suggest what settings or troubleshooting steps I can try to fix this slowdown?

I use tab groups actively and would save much of my work in my ever-growing list of tab groups. I saw today that many of them had disappeared. I wasn't signed into Firefox and nor do I have any different profiles made. I see two tab groups that I made yesterday but none from before that. How could this happen? How do I recover so much of the work I had saved up?

Since the last update on both my desktop and laptop web performance has slowed considerably. Some sites time out, some just don't connect. I've tried VPN on and off, changed security levels, deleted extensions to no avail. I use Windows 10. Is this the future with FF? Time, after many years using FF synced across all my devices, to bail?

Please advise soonest as this is more than frustrating and unproductive. Thanks Stephen

Just did a Mozilla update and noticed the Incognito Mode isn't working the same. I can click a link to New Private Window, but it looks exactly the same as a regular window. Incognito Mode was always purple which help me know I was in that mode. Anyone else notice this? Any suggestions? Thank you in advance.

I'm getting the following error message:

The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

I don't know what prompted this concern on my Windows 11-based laptop, but I only noticed this last night doing some research for another issue. I don't have any of my bookmarks showing up in the bookmarks section, nor will it allow me to click the star on any tab to bookmark the page. I have restarted and shut down my laptop several times and this is not solving the concern. Let me know if you need more information or if I need to start this inquiry again elsewhere, but again it sounds like the same concern.

I have included a screenshot of the exact error for accuracy's sake. Like everyone else here, I'm trying to get my bookmark and history access back up and running but not sure how to go about it.

I couldn't get past the first fix suggestion because I am not sure how to restart Firefox (https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional?as=u&utm_source=inproduct&redirectslug=The+bookmarks+and+history+system+will+not+be+functional&redirectlocale=en-US). I have restarted my laptop several times but the issue still persists.

Please advise.

Ironically, I am not having this issue on my older PC that is still operating on Windows 10. I can view history and access or add bookmarks with no concern to my knowledge.

Starting on June 9 2026 my Rockland Trust banking website will not open also other bank websites not opening or take several minutes to open, also other websites not opening. All these websites opened before June 9 2026. I have done all the recommended steps even uninstalling an reinstalling Firefox. What did Firefox do, as I had made no changes. I can open all these websites on other browsers, Google Chrome, Microsoft Edge, etc. I want to keep using Firefox but I can't if websites won't open. Clare O'Brien

Hello,

The fonts are not rendering properly on few websites, example(apnetv.xyz), everything was working fine with stable release of v146.

The beta versions were having the same issue, i assumed it was related to Beta releases, so I switched back to stable one. However now firefox has released stable v147, the issue persists. Kindly fix it.
