Firefox Support Forum

For about 6 months now, I've been having a strange problem with Firefox leaving behind ghost entries on the Win 11 taskbar.

I have a laptop attached to a dock which is connected to multiple monitors. If I have a FF window open on one of those external monitors and disconnect from the dock, all the tabs that were open in that FF window will become ghost entries on the taskbar. (see attached image).

It doesn't matter if I close FF entirely, these entries remain until I restart the computer. If I click on one of them, it opens up a brand new, blank FF window.

Has anyone else experienced this or have any idea what might be going on? I tried doing some investigating a few weeks back and I remember finding something in the task manager about COM Surrogate that seemed connected, but I didn't get beyond that.

At one time, I was able to swipe left on my trackpad and go back to the previous page on firefox. I can't seem to find where to set that preference. I'm running MacOS.

I’m using the official ShadowsocksX app to relay network connections through a Shadowsocks server, and Firefox seems to be having compatibility issues. The browser does not load pages when proxy settings are set to “auto-detect” or “use system:” I’m getting the “Unable to connect” error message. Manually setting the SOCKS host to 127.0.0.1:XXXXX does fix the problem, but that also means I have to switch back to “system” whenever I turn Shadowsocks off.

Neither Safari nor Chrome requires manual action to relay connections on the same computer.

On a different computer, I’m using the Outline client to connect to the same Shadowsocks instance. Firefox does not have issues with that.

i am using firefox developer edition version 126.0b3 (64-bit) on linux mint with an x11 desktop and for some reason the drag and drop breaks frequently.

i think i have figured out how i can consistently recreate the bug as well as sort of fix it temporarily.

i start with a newly launched browser. everything works fine. but then if i attempt to drag and drop something shortly after i drag and dropped something else and it did the little animation where it returns to its original position, i find that i cant drag and drop anything FROM firefox to anywhere else. and i also cannot rearrage tabs.

it seems to fix itself whenever I drag something from another program TO firefox successfully such as text into a textbox, or a .html file into the window to view it.

I have Firefox 124.0.2 running on Windows 11. For some reason, I can't update Firefox. When I manually download the update file, it appears to run Ok, but the version doesn't change. If I go to settings and click on "Check for Updates" is comes back and says Failed to Check for Updates. How do I fix this?

Originally reported on April 11th /questions/1444593: I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

I get the following message when going online with Firefox: "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've followed all the prompts to restart the computer, refresh the computer, delete the favicons.sqlite and places.sqlite and it won't allow me to delete them. This happened yesterday as well. Yesterday I could delete those files and everything was restored. But today I can't get it to work.

Lest update to 15.9 all my extensions are now disabled. Missing Lastpass and Surfshark from my menu bar. Doesn't seem to be any way to Enable them from Extensions screen.

I reloaded Lastpass from their site and this is now working on my Menu bar.

But what happened to cause this

Almost every time that I open a new session of Firefox I get a message that there is a problem and it needs a refresh, which removes the extension I use all the time. Any ideas why this keeps happening over and over and what I might to resolve the problem?

I received a scam Apple (security) popup (on which I never clicked) and from that point on, some 30+ obsolete tabs congregate across the top Firefox browser window. How do i lose all these unwanted tabs?

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

I was using Amazon just fine a few days ago. When I tried to open an amazon link yesterday, I got the message: Secure Connection Failed. I tried updating my browser and clearing my cache and cookies. Please fix

Hi,

I have managed to figure out ways to remove items from context menus from various pages here and around the web however it always seems to leave an additional unwanted separator line that I cannot find how to get rid of.

There are a number of additional lines I am looking to remove but the current one that is annoying me (based on most usage) is the additional line between 'Copy Link Without Site Tracking' and Search which is an add-on - Simple Context Search - https://tinyurl.com/yck5c (as shown in the attachment).

I did have 'search google for...' directly above the 'Search for Google' option which I removed.

I also removed 'Copy Link' which was above the 'Copy Link Without Site Tracking' option which I also removed.

Hope the above makes sense and any help greatfully appreciated.

Thank you

Greg
