Firefox supportforum

Figured out the basic issue (from Solutions here) why old Firefox not working on old XP-SP3. Found 52.9.0esr download - but when I run the file, it keeps telling me to "Close Firefox". Used Task Manager - nothing - not Firefox or anything else - is shown to be running. Any ideas? Might not be a Firefox issue, but would appreciate any insights. TIA - Jean

I need to copy browsing history and bookmarks from one laptop with FF v.60 to another laptop with FF v.52.

I know there are different ways of doing this, but in my case I don't have use of the source laptop. BUT, I do have the full profile saved in both laptops. I also had saved a json bookmarks copy, but it's 5 days old. No huge deal but I had some major restructuring of my bookmarks yesterday.

There's also sync, but I tried to just sync history and it does nothing. Plus I'm not sure if it's going to sync to "last updated" which is actually the other (destination) laptop with FF v52.

In my profile I see bookmarks clearly, but no history. They are both in places.sqlite? Should I just copy this? What else would be copied?

By the way, in bookmarkbackups folder, I see the last jsonlz4 file is from June 9 12:10 am, not June 10 12:10 am as it should have been perhaps. Does this jsonlz4 file work with the restore command of "import and backup"?

Thank you!

Hello,I have Windows XP 32 bit with service pack 3 and Firefox 52.9.1 ESR browser. Now that adobe flash player is history I can't play videos online that are not on youtube. I can still watch youtube videos.

Is there a HTML5 video player or something else I can install on this old system that will work or is that not possible? I know it's an old system but it still does the job.

Thanks.

I am running an old computer using XP. All I want to do on this computer is view Virtual Railfan live streaming videos. When I try to view a video, it says that my browser doesn't recognize any of the video formats available. Then it points me to a html5 faq. When I click on that I go to Firefox home page and it wants me to download Firefox. I already have downloaded the latest Firefox. Is there a workaround for this?
