I use the Selenium IDE plugin for my job about 1 year. But yesterday I encountered a problem. I saved the project I was working on and left work on Friday(10.10.2025). And for a year, I kept saving it to my desktop. Yesterday(13.10.2025) morning I restarted my computer because it was running very slow. When I turned on the computer, I saw that the Selenium IDE project file I was working on was missing. I say "lost" because when I had it checked by the system team at the company I work for, it didn't appear to have been deleted. Also, I don't have any files with the ".side" extension in the recycle bin. I tried to find it with programs like Recuva and Everything, but it is not found. This is a very important file for me and my work. Can you help me please?

File name: MevaTest.side Selenium Ide extension version: 3.17.4

Fedora froze and I had to reset my PC. Firefox hat quite a number of tabs open wich are still visible in history Recently closed tabs. When I click there on Reopen all tabs nothing happens.

How do I open all recently closed tabs?

I have been a Firefox user for many, many years. I started getting the Subject message: "The bookmarks and history system will not be functional" error message this evening. I started to "Fix" this error based on the Mozilla Support page. Actually, I first tried restarting my computer and that didn't correct the problem. I then noticed I could "sign off" Firefox which I thought I'd do and sign back in. I didn't notice until after the fact that my Firefox account was tied to a very old email address I once used that is no longer active "commish3@bellsouth.net". When I tried signing back into Firefox using that old email account, it said a security code would be sent to that old email address. Problem is I no longer have access to that email account.

1) Is there a way I can sign back in and have a security code sent to my current email address: tad3.dickinson@gmail.com ?

2) Can you assist with restoring my bookmarks. Again, years of building these bookmarks that I'm very dependent on.

Thanks, Tad Dickinson

Hi, All of a sudden, I lost absolutely all of my bookmarks. My PC is running Windows 11. My Firefox account was and still is logged in. At first, I thought the data loss was due to a CCleaner cleanup using their latest update. After the data was lost, I tried running another CCleaner cleanup, but this time it didn’t delete the bookmarks. So I honestly have no idea how this could have happened. These were bookmarks I had saved over many years... It’s a disaster.

On my linux system, I have two users. If I log in as user A and use FF and leave a bunch of tabs open, I can view those tabs again later if I restart my computer and log in as user A, so FF remembers its history.

No Problem Scenario Logged in as A - open FF - open a bunch of tabs - CLOSE FF log out of A log in as B - do stuff log out of B log in as A - open FF; all the tabs are there

Problem Scenario Logged in as A - open FF - open a bunch of tabs - leave FF open (don't close FF before...) log out of A log in as B - do stuff log out of B log in as A - open FF; all the tabs are GONE

If I run into the Problem Scenario, I can sometimes use these steps to get the history/tabs back. https://support.mozilla.org/en-US/kb/how-restore-browsing-session-backup

Whether the steps work or not, the Problem Scenario is annoying. I don't know what causes this. My desktop manager is KDE.

My father used my computer and synced all of his firefox “stuff”, i need to get rid of all of it.

I tried to log in, but came across a message that told me it would just merge with his stuff. I would like his bookmarks and passwords gone so that only mine occupy the browser.

Is there a reset?
