Or to open the profile selection sidebar?

I don't see it in about:keyboard but maybe there's something else somewhere.

If not, what's the quickest and easiest way to switch profiles?

I am having the problem a fix was created for previously where attempts to sign in to my google account continually redirect to a request to clear cache and cookies. Have done so multiple times, still can't log in. Can log in on Chrome so definitely a Firefox-specific issue.

We have resolved an issue with Google prompting users to ‘clear cookies and site data’ when logging in. A fix has been published, via Firefox remote settings that does not require a Firefox upgrade. Users will receive the update over the next 6hrs, if you would like to update immediately simply restart Firefox.

Note: The issue was related to CHIPS being enabled in Fx131, this feature has been temporarily disabled while we resolve the issues. Users who have disabled 'Allow Firefox to install and run studies' in Privacy & Security settings will need to enable to receive the update.

I recently made the switch to Firefox full time a few weeks ago, and in that time, I have been getting more and more annoying at how Firefox renders Youtube.com.

If I'm on my feed, and I click to watch a video, watch it and go back, I never know what I'm going to see when it goes back a page. Obviously it goes back to youtube.com, but I never know if it's going to load at the top of my feed, or about ten rows down. Even if I click a video in the very first row, and then go back a page, it may or may not load at the top of my feed. I could also actually click a video on the tenth row, and then when I go back, it might load at the top of my feed, though that is not as common, it has happened. It also sort of, kind of, reloads the page when it goes back, but never goes back to the point on my feed at the spot where the video I just watched is, as Chrome and Brave do.

This is not how Chrome or Brave do things, and yes, I know they use a different engine, and I'm sure that's the reason for this issue. Chrome or Brave, if I'm watching a video and click back to my feed, they are much better at loading what is in cache, even if I the video was on the 100th row. I can then manually refresh if I want to.

I am using Firefox on Linux Ubuntu 26.04. I normally work with multiple tabs. Then I quit Firefox with all tabs open at the point of quitting. Some times on the rare occasion there can be a forced quit due to some issues. In my settings I have configured it not to open the previous tabs. In fact I want a blank page. But whenever I reopen Firefox, it opens those tabs and tries to reload which is annoying. Some of these pages take a long time to reload, and why would I want to look at tabs which I already have read. Or if it crashes due to some website on a tab why reopen something that crashed in the place ? Can you fix this. Thanks.

Over the years I've added dozens of additional search engines; periodically I've "archived" lesser used search engines by toggling their visibility (to reduce clutter and speed up my search process), and when an "archived" engine becomes relevant to me again I've simply toggled the engine back to a visible state. However, as of version 152, this functionality appears to have been removed for user-added search engines. Is there a way to restore this functionality?

I've searched here and elsewhere on the web for a workaround, and perused the about:config variables, but have not been able to find anything. The show/hide functionality is still present for builtin search engines, so it seems like there must be some way to restore it for all search engines.

Thanks in advance for your help!

Subject: Firefox Sync appears to have erased all bookmarks after setting up a new Windows installation

Hello Mozilla Support,

I believe I have encountered a Firefox Sync issue that resulted in the loss of my entire bookmarks collection.

Here is exactly what happened:

I have been using Firefox Sync for several years without any issues. This was not my first Windows reinstallation. I have restored Firefox through Sync multiple times before. Firefox Sync had always synchronized bookmarks, passwords, history, extensions and open tabs correctly across my Windows PC and Android phone. I had approximately 350 bookmarks, organized into folders. Timeline Yesterday I performed a clean installation of Windows 11. I installed Firefox 152.0.5 (64-bit). I signed into my existing Firefox Account. I did not immediately enable Sync, so nothing was synchronized at that point. Today I enabled Sync and waited for the synchronization to complete. Passwords synchronized successfully. Browsing history synchronized successfully (it took a little longer). Extensions were restored successfully. Bookmarks never appeared.

Immediately after noticing this, I checked Firefox on my Android phone.

At first, one of the bookmark folders still showed that it contained more than 300 items (I saw the item count), but when I opened the folder it was completely empty. After synchronization finished, all bookmarks disappeared from both devices.

Additional information Browsing history is still present. Saved passwords are still present. Extensions are still present. Open tabs synchronization continues to work. Bookmark synchronization is enabled. I am signed into the correct Firefox Account. The second local Firefox profile is empty. The automatic bookmark backup now contains only the current state (7 items), indicating that the original backup has already been overwritten. The current profile contains both places.sqlite and places.sqlite-wal. The only Sync error log is related to a temporary DNS lookup failure (NS_ERROR_UNKNOWN_HOST) and contains no bookmark synchronization errors.

Because history, passwords and extensions synchronized correctly, this does not appear to be an account or authentication problem.

What concerns me most is that I briefly saw the bookmark folder still reporting over 300 items on Android before it became empty. This makes me suspect that something went wrong during bookmark synchronization rather than the bookmarks simply never existing on the server.

Could you please advise:

Is there any server-side recovery or investigation that can be performed for Firefox Sync bookmark data? Are there any diagnostic logs that I can provide? Is this a known issue with Firefox Sync after connecting a newly installed device?

I would greatly appreciate any assistance, as this bookmark collection had been accumulated over many years.

I have a Sync error log available: error-sync-1783454370913.txt

It only contains a DNS error related to tabs synchronization: NS_ERROR_UNKNOWN_HOST

There are no bookmark-related errors in the log.

Thank you.

Spellchecker does not function, and in my most important projects, Gemini and Substack, no spell checking takes place, I have to switch to Chrome of all things...here in this field spell-checking is taking place...why?

I have spent much time researching this issue, made all the intervention recommended, nothing works, and the failure is 'selective', works on many things, fails on important production browser interfacing.

I value being Chrome-free, please help me solve this issue

In Windows 10, FIREFOX is preventing the proper operation of the Windows 10 feature called MOUSE KEYS when FIREFOX is operating. MOUSE KEYS is a very important capability to individuals with certain disabilities.

MOUSE KEYS enables the use of the numbered keys on the NUMERIC KEYPAD to be used to move the cursor around when the NUM LOCK key is turned ON, as a substitute for using a mouse. Does Mozilla have a way to prevent FIREFOX from defeating this MOUSE KEYS feature?

Google AI indicated that there is a solution specifically for FIREFOX. That capability is built into FIREFOX and begins by using "about:config" to reset a parameter named "permissions.default.shortcuts" from either "0" or "1" to "2". I successfully implemented the steps in this solution by changing that value from its default value of "0" in my computer system, to "2", but no change resulted. MOUSE KEYS continued to malfunction in the same way.

After exhaustive testing looking for a pattern, I finally found one. The malfunction appears to be the following: With the MOUSE KEYS feature activated in the WINDOWS 10 set up, and with NUM LOCK turned ON to assure that this function is ON, each of the numeric keys, 0 through 9 on the keypad, cycles through the different MOUSE KEYS functions of all ten of these keys, in ascending order by their number. For example, if you press key 7 for ten times in a row, it will cycle through each of the ten MOUSE KEYS functions associated with the keys 0-9 to occur, returning on the tenth press to the function that was executed the first time that key 7 was pressed, and so one endlessly through multiple cycles. And similarly for each of the other ten numbered keys.

A similar type of malfunction of MOUSE KEYS occurs with any BROWSER program that I have tried, including GOOGLE CHROME and BRAVE. I gather from GOOGLE AI that browser programs INTERCEPT the codes generated by the numeric keys on the numeric key pad and change those codes before sending the codes to the WINDOWS 10 operating system, and thus to MOUSE KEYS, for execution, causing this problem.

Is there a solution for FIREFOX what will restore the proper function of the MOUSE KEYS feature of Windows 10, when FIREFOX is being used? Thank you for any help that you can provide.

Windows 11 expensive high performance tower PC. When I am closing Firefox I am warned that I am about to close 80+ tabs although. I actually had only 13 tab groups (closed) and one ordinary tab open (The New York Times) I close Firefox anyway and ALL the group tabs disappeared.

Sometimes, when I am warned that I am closing 80+ tabs, they luckily they haven't disappeared upon restarting Firefox. This happens often.

I know how to reconstruct my tab Groups proceeding from listing all tabs.

Sometimes the tab groups don't disappear. It makes no difference whether I start a Firefox session on my just rebooted PC (and run PC for a minutes only using Firefox) or not. When I recently closed Firefox I could see from task manager that there was minor activity showing in the Firefox app which surprised me. I hope you have an idea of what might be occurring. I'm not a novice, I purchased my first PC in 1989

Thank you, Anita

I tried to use 'Change location' in the weather widget on the New tab page. I can type my location name in the search box, but it doesn't give any results. Thanks for reading my question!

Hi,

After the last two updates, the **Pseudo-elements** tab in the Browser Console can no longer be closed once it has been opened, and vice versa.

Please see the video below demonstrating the issue:

Thanks.

This is a recent problem but when I try to open new tabs they don't load or take a very long time to load. I wind up shutting down my computer and resarting but sometimes that doesn't help. it seems to be getting worse. I do not use any other VPN but yours and Duckduckgo to search. I use a macbook air. Any suggestions? Thanks

On my personal computer, I have a Profile for work and I was logged in via a Mozilla account using my work email address

I've recently set up a similar thing on my work computer. Signed in using Mozilla account. I have since noticed that on my personal computer it says "Account disconnected."

I'd like to sign in again and sync them so that I always see the same settings, shortcuts, open tabs etc on both computers. But if I sign in right now, will I lose the customizations I've made on the work computer? Which computer will it consider to be the "source" of the newly synced information?

I had lots of trouble making Firefox work yesterday, after what I believe was a Mozilla update I had to uninstall and then reinstall. What I am experiencing after the new install and all updates is: I placed the icon on the taskbar. when I open Firefox it opens a new icon in the taskbar. I have two icons when using firefox instead of two like it has always been before. In the picture, the icon on the left is always there. The one on the right opens when I open firefox. Is it supposed to work like this? It is a windows issue? Is it A mozilla issue? Anyone else having this issue. I have tried different ways after deleting the icons, to place it back on the taskbar. I used the pin to taskbar, drag and drop on taskbar... Any ideas. Just live with it? or fix it somehow?
