Firefox Community Forum

An hour ago I had all of my Firefox bookmarks. Ten years of meticulously filed and regularly culled references that I use multiple times daily. I rarely log out of Firefox sync, so that I can keep them up to date.

I now have no bookmarks and no tags.

For some context, two things just happened simultaneously. So, I'm not entirely sure which is the culprit.

1) Firefox just updated and I rebooted my computer.

2) Norton 360 updated sometime in the past two days. I attempted to familiarise myself with the new interface. Foolishly, given the track record of Norton-360-for-breaking-your-games, I ran the disc cleanup, which recommended I remove approximately 400 Mb of data. Norton stated this data was temporary files. If they were indeed my bookmark history, nowhere did Norton indicate they were bookmarks. Also, never have I encountered a disc cleanup that wholesale wipes bookmarks. I do hope Norton is not the culprit and this is just a glitch, because if this were due to Norton having no safety net for deleting an entire library of bookmarks - and they can't help me restore them - then that will be the final nail in the coffin for me doing business with Norton.

The suggestion to go to Import and Backup in Firefox, then click Restore, offers only the option of Choose file... - and then launches nothing.

Currently, I'm seeking any means of restoring my bookmarks. Any help would be appreciated.

I had presumed that I was taking reasonable measures through my Firefox Sync settings to protect my bookmarks and ensure they could be restored in the event of accidents. If these bookmarks are permanently lost, the amount of work I've just lost is quite the blow.

Edit No. 01: After writing this, my Bookmarks Toolbar is also now empty. Perhaps it had wiped earlier, but was merely waiting for a refresh to take effect.

Edit No. 02: Also, it seems I am unable to create any new bookmarks. I shall read the help suggestions relating to that now, to see if it's a relevant issue.

Good day, The issues that I am encountering are explained below. The solution found after hours of research is uBlock Origin : https://ublockorigin.com/. Do you know which filters and rules should be applied to exclude the Wikimedia Foundation and all of its derivatives from the results provided by my search engine? Please share your knowledge. Sincerely. ________________________________________________________________________________________________________________________ I am utilizing Firefox ESR 128.10 desktop version on the Linux operating system. I wish to conduct research on the internet, utilizing the Startpage search engine. I would like to exclude the following sites from my search results: wikipedia.org, the Wikimedia Foundation, and any affiliated websites, regardless of the language or location settings configured.

What is the correct approach to establish a customized Startpage search profile excluding all Wikimedia Foundation sites? What is the proper setting to create a persistent and customized search engine configuration that excludes all Wikimedia Foundation domains even after an operating system update or reinstallation? Is it permitted to manually manage a customized search engine?

I have been advised to utilize an add-on or create a dedicated profile.

What would be the most suitable solution in my case, and the one that will be the most effective and stable ?

It is unfortunate that mozilla-firefox does not appear to offer a 'blacklist' or exclusion list feature, as that would be the most direct approach to excluding the Wikimedia Foundation websites from the search results.

I thank you kindly for all of your suggestions and responses to come. ______________________________________________________________________________________________________________________

Hi

I've just booted my machine and opened Firefox, only to be presented with a completely fresh install.

All my settings, bookmarks and history gone. It was fine yesterday when I closed it and powered down.

I'm running Kubuntu, I've checked the .mozilla folder and nothing...it's like my profile has just been overwritten.

Not happy at all, I'm starting to dislike Firefox.

Can anyone offer any help or advice please?

Thanks in advance.

Hello. In the past two days I lose my tabs when I shut down Firefox. I used to be fine using the X at the top right and when I restarted the browser, all my tabs would still be there. Then they started going missing, so I started using the menu option to exit the browser. The tabs still went missing.

Then I noticed the square icon button on the extreme left and have discovered that Firefox has different windows, and that one of them (see attached image) has all my tabs in it, while the current window does not.

I cannot change Window 2 to be the current window. There is no obvious function on the page, nothing in settings and google is useless - I just get pages of discussion of how to tab between different apps on the desktop.

How do I make Window 2 the current window? See image.

Thank you

I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

I've got Reading the full Article on GROUP TABS that has been released yesterday on My Firefox it Got Update and Installed But I just couldn't found the "Add to the Group option when I click right at any of my tab" + If I drag over one on Another Tab it just got replaced like they substitute their Places No BOX Border line Shows No Group Created NOTHING. I'm a Nearly 6 Year Old Firefox User I NEEDED that FEATURE SO BADLY PLEASE FIX it SOMEHOW. ThAnks Regards: Loyal USer

I received this download from Firefox today, July 22, 2025: xRqj7qhl.html - Size: zero bytes - Kind: HTML text . I've never experienced this before. Is it legitimate? Thanks

I'm running Firefox browser 88.0 (64) bit, and have been trying since before Xmas to upgrade it to a newer version. It's installed on an older Dell laptop running Ubuntu 16.04 LTS (which I've also tried repeatedly to upgrade without success).

I've tried to upgrade both through the UI, but also tried using the command line in Terminal. Per advice in other threads, I've found the best mirror site and changed my settings to use that, but still no luck. Even the preliminary "sudo apt update" via Terminal fails; the first error tells me that the public key is not available. I assume that's the place to start, but don't know how to correct it.

I'm up against the deadline for updating my browser, and would very much appreciate any help you can provide. (Please note that I'm posting from a newer computer, so automatically generated info about my system won't apply. See the screenshots for that info).

Hello, Sorry to disturb but its been two days and I am unable to access my Google accounts (work and private) through Firefox in anyway. I have done all the basic fixes I can think of but with no success. I have deleted caches, checked plug ins, rebooted Firefox went through the trouble shooting mode, followed advice in the community forum, tried logging in from Google linked accounts. Spoke to our internal IT support at work but nothing has solved the issue as yet, spoke to Google support.

My assumption is that it has to be the browser as I am able to log into google with another browser but Firefox is my preferred browser and would like to use it again as such.

Please advise.

Thank you Cait

All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

Hello, I'm having a problem on Windows 10. It's a fresh windows installation and I tried already some solutions: reinstalling firefox, deleting cache, refreshing firefox, private windows, no add ons, trouble shoot mod. Nothing helped. The problem seems to be with live stream, either on twitch.tv or youtube.

FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?

Hello, At one time I could login at home to view my Spectrum.net account on Firefox (default browser), now I get a popup which reads "This feature is currently unavailable. Please try again from home or contact us for assistance. "IDID-4000"

I get the same message on my laptop and desktop, both running Firefox. I can switch to the Edge browser and login with no issues. I have cleared cookies and used other suggestions I have read on the web, but to no avail. Any help would be appreciated!

Thanks! Tony

Due to relevant policy and legal reasons, the Chinese version of Firefox has been used https://accounts.firefox.com.cn/ As a login account URL, it is also used in the international version https://accounts.firefox.com As login URLs, the two accounts are not interconnected. After recently upgrading to a new computer and downloading Firefox again, I am unable to use the synchronization function https://accounts.firefox.com.cn/ Login to the account, the specific manifestation is to enter the correct password when logging in, and it will continue to display 'processing'. But by directly entering the above website address, you can log in to your account normally. I now need a solution to the synchronization issue by moving bookmarks, plugins, themes, and synchronized tabs from my previous Firefox computer to my new computer.

由于相关政策法方面原因，中国版的firefox使用了https://accounts.firefox.com.cn/作为登陆账户网址，同时而国际版使用https://accounts.firefox.com作为登陆网址，两者账户不互通。

最近换了新的电脑以后，重新下载firefox，使用同步功能时，无法使用https://accounts.firefox.com.cn/登陆账户，具体表现是登陆时输入正确密码后登陆，一直显示处理中。但是直接输入上述网址，可以正常登陆账户。

我现在需要可以解决同步问题的方法，将我原来电脑中firefox中的书签，插件，主题以及同步的标签页移动到新电脑中。

I have run across threads with similar questions in both mozilla support and reddit, but as they are old and archived I cannot add additional info or request clarification, so here is (yet another) new one- I understand you can go into manage data in settings to delete what you want, however in mine it only shows a handful of most recent (opened today or currently open) since my settings clears history and deletes cookies upon exiting ff.

Cookies and Site Data section shows only 40.7mb of data is stored and in Manage Data only shows 8 sites... Clear Data area, with only these two boxes selected (attached) and 'everything' (time) still only around 50mb. My storage/default folder has 1005 folders and the data is over 1.5gb; I would like to manually delete all of this and as others have tried to ask, am wondering if this is ok to manually select them and delete in windows, or using windows %appdata%(?) and if so, will the sync feature (if I just clicked 'sync now') still retain all my bookmarks when I relaunch ff? Not concerned about any browsing/form history or passwords, only bookmarks.
