Ever since the last update of the Firefox program, I am frequently getting the "Server Not Found" message when I click on links online. If I switch browsers, the links work just fine so it is obviously Mozilla's problem and not anything with my "modem or router" as I am told int he "what can you do about it" message on this error. Mozilla needs to look into this problem and update whatever is causing the failure to link message.

I use a SAAS solution for my small business (FreshBooks) that has not been working well with Firefox as of late. When I reached out to their customer care department they asked me to follow their resolution steps, which included wiping the cache and cookies for all of my Firefox browser. I did so at their request, it did not fix their issue (it appears to be something their developers are working on solving) and subsequently I lost a lot of retained other sites log-in and history. Is there a way to restore the cache cookies that were removed yesterday? Appreciate your help,

The full winget command is: ```pwsh winget install --id Mozilla.Firefox.zh-CN -s winget -e -i -l D:/.../Mozilla/Firefox/ ```

The winget log mentioned that winget downloaded https://download-installer.cdn.mozilla.net/pub/firefox/releases/150.0.2/win64/zh-CN/Firefox%20Setup%20150.0.2.exe ```log 2026-05-12 22:19:28.840 [CORE] WinINet downloading from url: https://download-installer.cdn.mozilla.net/pub/firefox/releases/150.0.2/win64/zh-CN/Firefox%20Setup%20150.0.2.exe 2026-05-12 22:37:42.091 [CORE] Download hash: 6c7fb833ebb13637daf750c7a2c611e2b6d8d324dc2463eed40e8478d0c791fc 2026-05-12 22:37:42.091 [CORE] Download completed. 2026-05-12 22:37:42.094 [CLI ] Installer hash verified ```

Then winget shows the installation was successful, but the shortcuts in the Start menu and on the desktop point to a path that doesn't exist. I noticed that this path is the one I passed to winget via the -l parameter, but it is missing the slash (`/`) > D:/a/b/Mozilla/Firefox/ → D:\abMozillaFirefox\ I couldn't find the installed Firefox either in the root directory of drive D or under the originally expected path D:\...\Mozilla\Firefox.

Although I passed the -i parameter (specifying interactive installation) to winget, I didn't see the installer window. In the user registry, the installer also wrote the aforementioned incorrect path, and I cannot uninstall this installation through Windows Settings.

I wrote a script myself to search for folders or files with 'firefox' in the name (case-insensitive) on my system's C and D drives, and I only found this folder that looks related: ```pwsh > ls "C:\Users\...\AppData\Roaming\Mozilla\Firefox"

   Directory: C:\Users\...\AppData\Roaming\Mozilla\Firefox

I want to know what the installer does after running the above installation, and how I can undo these changes to reinstall Firefox?

Firefox FREQUENTLY totally removes added applications attached and it totally screw up my ability to access anything when you remove my Bitdefender application from access then I have to again EXPLORE added applicaitons!!

i've seen this before, in different older machines, but i can't remember the remedy. possibly a mouse-screen problem. it started with 150 i think...

Also in youtube, a gray layer covers the selections rendering mouse clicks impossible. clcking the logo, page reloads, but soon the layer covers most of the page. resetting graphics had no result.

thanks

i'm using mf 150

This issue started a few weeks ago. Frequently, when I switch from one page to another, I get a pop-up page from some unrelated business or form. I have started to fill out an order form for a trusted business only to find out I am filling out another company's form instead. My page gets hijacked in this manner several times a day. It's not only annoying, but a security issue. One moving company keeps popping up. I am not moving, or even thinking about moving, but I keep getting this company's home page when trying to access other venues.

I don't know if this is related, but I installed Duck Duck Go a while back to avoid Google trackers. A few weeks ago I found that Duck Duck was no longer my preferred search engine and put it back as preferred. Whether coincidence or not, my problems began about that time.

Please help.

Good evening,

I'm going to install the applicatioin because it hasn't been working for several monnths ( it doesn't work anymore ). For exemple , if I want to watch Netflix and the video starts playing , there's no picture, it just loops and the screen is black.

I've tried everything turning off the computer, closing Netflix, even Youtube . I'm at a loss.

Thank you

So every few days now if the free VPN is on I get my tabs locked into an error. I get that warning screen and sites stop loading or partly load, before the VPN update I never had to close Firefox this often, if left idle with the VPN on this seems to happen faster, I have left the VPN on overnight and I tend to nearly 90% of the time wake up to this error, if I disable the VPN fully I can pick up where I was but cutting it back on I have high odds that it will break, Firefox is idle while I do other stuff and the VPN is on, I get that error and I get to watch the weather app give me it's error. I have never had Firefox fight my antivirus It worked fine for ages, and only now do I need to reset Firefox by force now every 1 to 3 days. I use to be able to leave tabs open, but now they always error out in a few days. It could be other things, I just never had problems like this until now, it's so common and in the same time tables.

I use the current version of Firefox on Ubuntu 22.04 Linux. When I scroll down past the individual bookmarks at the end of the menu, the folder names start repeating, along with the bookmarks inside them. I have three or four sets of bookmarks and would like to have only one. How can I delete all the bookmark folders below a certain point? By the way, when I install a new, different version of the operating system and sign in Sync restores all the bookmarks.

I was getting popping in audio both in Smplayer & videos on other sites. I discovered the problem went away completely when I closed the X tab. When it was open, I noticed another glitch. I keep a small video windows to keep track of my sleep time. The elapsed time is displayed on them. Only when X was open it was throwing it off by about 3 seconds a minute. I closed it in Firefox & signed onto X on Chrome & all these problems went away. This is the only web site that has ever done anything like this. What is Firefox's problem with X?

How to sort Tab Groups alphabetically in the Add Tab to Group Menu?

I want to add tabs to groups bit the groups are changing their position and it would be very helpful to (optionally) have the freedom to sort Tab Groups to appear alphabetically in that menu!

But that should NOT affect the sorting order in the browser window!

But of course it also would be helpful to have the freedom to also sort the tab groups order in the main windows, but please make it a different sort order than in the Add to Tab Group menu dropdown.

Thanks!

I use multiple Firefox profiles and create separate desktop shortcuts for each profile using Firefox’s built-in profile shortcut option. I then pin each profile shortcut to the Windows taskbar so I can launch them independently.

The issue is that when I click one of the pinned profile icons, Firefox opens a new separate taskbar group/icon instead of attaching the window to the already pinned taskbar item for that specific profile.

For example:

• I pin Profile A and Profile B separately to the taskbar.
• When Profile A is already open and I click its pinned icon again, Windows creates another Firefox taskbar button/group instead of reusing the existing pinned Profile A button.
• Google Chrome profiles do not behave this way on Windows — each profile stays grouped with its own pinned taskbar icon as expected.

Is this a known limitation/bug with Firefox profiles on Windows taskbar integration, or is there a way to make Firefox profile shortcuts behave like Chrome profile shortcuts?

There was an update with Mozilla Firefox on the 8th. I had tabs open on the computer. After the update, I could not retrieve the tabs I had open. Tried to restore and nothing worked. Is there any way to restore my tabs?

When changing tags in Microsoft 365 Term Store, the changes are not showing on the respective Sharepoint sites and lists when displayed in Firefox. The tags still show the old values. Refreshing the page and deleting the cache does not solve the issue. Only uninstalling and then reinstalling Firefox resolves the issue. The problem does not occur in Microsoft Edge.

It seems that a few days ago my Firefox was (involuntarily) updated in the course of another update (Linux): Previously, after Ctrl-S I could immediately start editing the name of the downloaded .html file, usually replacing it: the .html was retained, but the main part was highlighted and replaced automatically with the first typed character. Now one has to highlight the name with "select all" and also take care of the .html suffix. This is highly inconvenient if one wants to change the (usually) much too long names. Is there a chance (option?) to get the old behaviour back? (By the way, not connected with this change: It is annoying that Firefox silently changes `:` to `_´ in desired names though these are perfectly legal in Linux.) (and I would like to be able to use Firefox save to command from the command line.
