This question relates to version 134.0.2 (64-bit). This morning I started Firefox and found that many of my bookmarks were missing. On trying to restore from the program automatic backups, I get the repeated message "Unable to process the backup file." On examination, the files, while not in ASCII, appear to contain ASCII text strings recognizable from the bookmark descriptions. They are not, at least, empty. Unfortunately, I do not have an HTML format backup. Any idea why none of the backups work or what options I have? Thanks in advance.

Starting early this morning I could not open a website (where I purchase supplements) I have accessed in the recent past. I added the address to the DNS listing but that didn't help. In the verification lock icon in front of the address it says the connection is secure. But below it states the Connection verified by a certificate issuer that is not recognized by Mozilla. Prior to 1/22/25, I had no issues opening this or other websites. It doesn't matter if I have my VPN turned off or not, the website does not open. Was the Mozilla update of 1/22 the cause? If so, how do I rectify the issue I currently have? If not, how do I rectify the issue I have?

When using the PiP feature is there a way to switch whether it pauses the video when closing the PiP player?

Often if i want the audio to continue but dont want the popout player there and if I press the close button it will just stop the audio. If I select the PiP window and use the shortcut CTRL + SHIFT + ] the audio will continue playing as I want it however this is inconvenient and requires using the keyboard, is there any way to change it so that closing the popout player doesn't stop the tab from playing audio?

i have Linux Cinnamon 22 and want to stop the PIP on YT. I disabled/unchecked box for PIP on FFox and PIP still happen on YT. What can i do to stop this horrible PIP now ? thank you.

I get bills in PDF form from my water and gas provider. When I pay the bills I use Adobe to add a "PAID" sticker and a comment indicating when the bill was paid, and then I save the PDF (from Adobe) with the newly added comment. Previously I was able to open these PDFs in Firefox and the contents of the comment (added via Adobe) was visible; however, recently when I used Adobe to add a comment to a PDF and then opened it in Firefox the contents of the comment were not displayed (NOTE: I opened the PDF in Edge and it displays the contents of the comment, but it doesn't display with the same wrapping as used when the comment was created in Adobe). Interestingly, older PDFs that I added comments to still open correctly in Firefox i.e. they display the contents of the comment. I am assuming there has been some sort of update to Adobe, and was wondering if there needs to be an update to Firefox to continue to allow the contents of comments in the PDF to be displayed.

Wikipedia render Thai fonts correctly. But it seems to render Latin texts and numbers in "TH Charm of AU" font for Thai articles, which I did not set anywhere in the browser (and my operating system). Ticking "Allow pages to choose their own fonts, instead of your selections above" does not fix it either. But it renders fonts correctly in English version of the same article. (See the attached images).

Any ways to fix this?

Thanks in advance.

since firefox 133.0.3 i can no longer use video controls in youtube. youtube video controls (scrolling an sound volume) work when youtube is in firefox picture in picture mode. when picture in picture is disabled in firefox settings youtube controls still not work.

thx for forcing me to use a feature i do not want. pls fix this.

Everytime I open firefox i have to enable Picture-in-picture in settings, because it somehow gets dissabled everytime i close out of firefox, its annoying and I dont how to fix it, and cant find anyone else having this same problem.
