Hi, my session with a lot of open tabs has been lost due to a crash. In the profile folder, the recovery and previous files in the sessionstore-backups have been deleted. I tried to recover them using shadow explorer, but these files are corrupted, so I've had no success reading them. Is there a way to fix the corrupted files? Alternatively, because I've had sync enabled for open tabs, is there a log for past open tab synchronizations? If this was stored on the cloud, it may be possible to retrieve that table and restore the list of open tabs that way?

I'm simply trying to email someone using the email link on their site.

The link is a mailto link which requires an email application (which I don't have). All I want is to copy the link to the clipboard.

Firefox lets me right click the link and copy the email address, but this doesn't allow me to provide the required Subject specified by the site's author.

I could have sworn Firefox used to have this feature. Netscape and IE certainly always had it back in the day.

I am using Firefox desktop on Windows 11. I have downloaded hundreds of articles from this website, with no problem until yesterday. I accessed the website using Edge, and it worked fine.

When trying to access a particular article to download it to Ancestry, the following message appears:

Application error: a client-side exception has occurred (see the browser console for more information).

I accessed the browser console for more information, which I'm sure someone can understand, but not this grandma. This is what I got:

Your PC doesn't have an app that can open this link. Try looking for a compatible app in the Microsoft Store.

Is this Microsofts way of saying "Use Edge?" Can I change settings to make it work?

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.

I'm experiencing an issue when copying PNG images only in the Firefox browser. Here's the problem: When I copy a PNG image and paste it into Photoshop or any other program, I get an image with a black background.

This didn’t happen before, but it started occurring after a few recent updates.

In other browsers, I get a “normal” PNG image with a transparent background.

I have my FF preferences setting as "Strict". But somehow Facebook people were able to hack into my FF account, and obtain my password for FB and other passwords? This comes directly from my Firefox preference page Red Warming Box includes & states on Sept 30, 2025 Facebook Hacked & Gained access to my account. Not a person, it states Facebook did it. And to change my FB password ASAP. So I go to my FB account go through their lame motions and they say they will not allow me to do so because I haven't used my account very long and they don't know if it is me trying to change my password. My question is what do I do now and how to prevent any social media outlet of simply hacking into my Mozilla account or my Firefox accounts? Please help. Seems like their should be a law against this type of intrusion gathering save password and etc.

Windows 11 23H2 - Firefox 131.0.3

I use firefox on laptop with a usb keyboard, On the laptop CTRL+Shift+P using Left CTRL+Shift+P and Right CTRL+Shift+P works as intended and opens a private window.

However on the usb keyboard using the Left CTRL+Shift+P doesn't work to open a private window while the Right CTRL+Shift+P works normally.

After a bit of trial and error i worked out the issue with the usb keyboard is the left CTRL key. It works for other shortcuts such as CTRL P but just not for the new private window command.

I tried loading firefox in troubleshoot mode to see if this was an addon issue, still no good. Tried 2 different keyboards from the one i use daily just to see what would happen and still the same issue.

Any suggestions? im at a loss.
