Firefox Community Forum

I tried updating Firefox and it failed me. At the end of the day of work I did an automatic update. I shutdown my computer and the next day Firefox worked intermittently as in it would load pages and some it wouldn't load. I thought it was my internet connection and verified in another browser. The internet connection was okay, it was a Firefox issue. Then I notice the Firefox icon was a generic icon. I'm now lost all my bookmarks, which I thought I had in Firefox sync and open windows / tabs. This is a bit frustration that Firefox failed like this and caused me to lose data.

I have a Windows 7 PC. IE no longer works. I would like to use Firefox to access the Internet. Firefox offers a version for download. I got it using my Windows 11 PC, however it fails saying that it can only be installed on Windows 10. Can this be fixed? I cannot access the Internet from my Windows 7 PC.

With the latest update to Firefox, 147.0.1, our test suites run with the extension, Selenium IDE, has errors, "Failed:n.createEvent(...).initKeyEvent is not a function". I am running the latest version of Selenium IDE. Installing the previous version of FF has no errors. What is the solution?

After running cc cleaner and even that i de select the book mark and side setting the Firefox Bookmars and history is non functional . i did create a new profile yesterday biut today i have the same Issue. I uninstalled CC CLeaner but i want to restore my Bookmarks system i need help with that. the explanation here are not really helpful

I am trying to access certain HTTPS website and some of them show PR_CONNECT_RESET_ERROR in Firefox. This error is not present in Edge or Chrome. Any ideas on what could be the problem?

An error occurred during a connection to delta-executorr.com. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

Here's what I've tried (none of these works):

   DNS over HTTPS turned off
   Uninstall all add-ons
   Reinstall Firefox
   Create new profile and set it as default
   Delete/rename certs.db in the Firefox profiles folder. 

I'm tired fixing errors which become more complex and solutions are written for people who have the time an knowledge to waste fixing these constant issues in FIREFOX, Time to change browser.

I don't know if this is relevant but one of the website that does not work is https://delta-executorr.com/

firefox doesnt start and gives me this error If i uninstall the have a fresh, install, everything will work normally until i restart my pc

Aloha — An update to Firefox must have occurred, and I am unable to access my open tabs and bookmarks. I have had a Firefox account for 15 years at least and a lot of information was in my folders and bookmarks. Please let me know how the information can be recovered. I tried to follow several of the instructions provided and was not able to fix the issue. I have a recovery code/Mozilla key, but I am not sure where or how to use it.

I do all my work and personal stuff on Firefox so I need timely assistance to fix the problem.

Thank you, Mike

I'm not exactly clueless, but I'm not an engineer. For some reason, I had three open Firefox/Mozilla browsers open on the taskbar but connected to one icon. Today, I've lost the browser with all of my frequently used sites, and tons of research, family, friends, World War II, finances, etc. The other two browsers had one tab, and maybe ten-fifteen tabs, respectively.

How do I restore the main browser?

Thank you for any assistance.

i have lost my Bookmarks folder and the bookmark function no longer works, since recently restarting. CAN ANYONE HELP ME TO RECOVER THE LOST BOOKMARKS OR HELP ME WITH THE ACT OF BOOKMARKING?
