Diễn đàn hỗ trợ Firefox

After the latest auto update all of my history, tabs/windows, and bookmarks were deleted and I can't recover them. I have tried importing bookmarks and it does not allow me to upload an old data file and I can't restore my previous session. I tried checking both profiles but neither had my information saved and now when I open the about:profiles says "Another copy of Firefox has made changes to profiles. You must restart Firefox before making more changes."

I'm scared to try anything else because I don't want to mess anything up further but I really need my tabs and history back.

I restarted my computer and then reopened firefox and it had updated and I noticed my bookmarks were gone but my windows/tabs were open, so I tried to choose a file on the bookmark backup and nothing was happening so I restarted and after that all my history and tabs were gone and I couldn't restore them.

Dear Community,

Since more than a month, when firefox was updated, all my bookmarks seem to be gone,which includes a lot of valuable research made over the past few years.

I have tried all suggestions that google give me to restore my bookmarks, but as far as I understand, there are no newer ones since 2019 (nor older ones than 2018) on my computer? That's what I find in a folder called 'bookmarkbackups' with json-files. Separately I also searched for 'json' and '.jsonlz4' and found nothing after 2019. Also I searched for .html, but nothing seemed to contain bookmark directly.

When I go to manage bookmarks > 'import/export' icon in the upper bar, it suggests two options, for 'nov 13 2025', or today's date), of which none provide me with any bookmarks.

Can I somehow still recover my research?

Do I really need to backup manually?

Or need I start saving all URLs in a word-document for my new research project?...

Firefox seems to update regularly, I currently have version 145.01. (I work on a Mac 2021, with Ventura 13.7.8)

I highly appreciate any advice on this matter.

Kind regards, Maria

There is a left side hidden toolbar that has history AI etc pictured below. I removed it on another computer by mistake and can't figure out how to get it back. It is on a Windows 11 machine. Thank you for any help.

One page of my online scheduling software often doesn't load all the way. It's a list of clients, not super-long. It often only loads the first 10-15 names (out of about 80). Eventually this pop-up appears: "This page is slowing down Firefox. To speed up your browser, stop this page."

I'm on a Windows 10 desktop with PLENTY of speed/memory. That's not the issue, unless Firefox isn't using the computer optimally.

I've been having tons of issues with Firefox so a few days ago I did a "Refresh." This helped, but obviously didn't fix this particular issue.

How do I minimize the web page when I don't see the usual icon at the top of the page. Now, I've attached a screen shot that does not show any icon of other means of minimizing that screen. I'm running Windows 11 and WORD 2021.

The screen appears on Opera and Google Chrome with the icons. Thanks.

I have just bought NordPass password manager after seeing it the best recommended on a website. Then I find that Firefox does not recommend it. Does Firefox have a password manager ?

Hi Mozilla team! I have a problem which started happening recently, or at least I didn't realize it before. I went through all the articles, tried adjusting density in Customize Toolbar, went through all the settings with systematic approach with ChatGPT, some things in about:config and even tried adding userChrome.css in profile folder but nothing helped.

The problem is that I have PC with dual screen setup, one is 1440p, 125% zoom in windows settings (main) and 1080p, 100% zoom in Windows settings (secondary). When I change both screens to same zoom, everything is fine, but when it's set up like this, on secondary monitor (1080p one) tabs in open browser don't reach top of the screen, in fullscreen mode, that is, I need to move mouse downwards if I want to middle click open new tab or close old one or even simply move between tabs. It's like, it doesn't reach top of the screen for few pixels - it has a ghost gap.

I don't have this problem in any other browser, tried Chrome, Edge... I would like to continue using Mozilla, but this is bothering me. Could you please consider fixing it in some of future releases?

Thank you in advance!

Hi! ...I would like to get rid of that little icon/button (because I already have Fifo on mobile, thanks!) How can I do it? Regards and thank you

My computer, being 7 years old (and without the space to upgrade to WIN11), has always been a bit slow with low RAM and storage. The swap from Chrome to Firefox essentially gave it a second life, as Firefox didn't need a lot of space to run. Recently, though, it locks up with almost every search, refusing to let me x out a tab and try to save myself for 3 minutes or more, and the bluescreens have come back, too. If chrome hasn't also gotten worse, I'm considering switching back. Does anyone know what happened? I haven't installed anything new.

It's really frustrating and disappointing, because I thought I had a solution when I swapped to Firefox.

Just updated my Firefox. I had a huge tab group saved, and tons of bookmarks. I've been using firefox for months, I didn't have an account signed in on the browser though. I updated it and it had to restart, and everything was gone when it reopened. I even clicked that it should reopen tabs after restarting, but it just opened to tell me to make a profile. It told me that they just introduced profiles, and it put me on profile 1, which looked brand new. No browsing history whatsoever, no bookmarks, my background that I set is gone, and I cannot find anythign at all. I had over 50 bookmarks, inclyding very imprtant links for a final paper, and I'm genuinely so upset. Multiple of those bookmarks were things for me to go back to read/watch later and I will literally not be able to find them. If anyone has any tips at all, I'd love them. I am so seriously upset right now and I'm just hoping its possible for that to come back.

At least once a day since Version 145 dropped Firefox has told me I need to restart to update. When I do, it shows a pop up telling my I am opening an older version of Firefox and need to create a new profile to avoid corrupting my data. Daily, sometimes twice a day I have to go in and switch profiles back to the profile that has all of my book marks. Every computer in our office has this issue now. One of them deleted a profile without prompting, and it is not even in the appdata folder with "deleteme" in front of it. It is just gone. The last update had tabs crash daily. Is there any hope of stopping the second broken update in a row from wasting my time fixing it every day?
