AdBlock has not made any updates for Firefox for eleven months. Do they just not care, or has Mozilla rejected them? The internet is terrible enough as it loves to scam all users on all sites.

Autofill has been working perfectly fine until yesterday. There's not even a manage addresses in the privacy and security settings anymore.

Autofill card still works, but not addresses.

For years, I have used print to pdf in Firefox to generate pdf files of long web pages. It always worked. But lately, I noticed that huge numbers of blank pages are inserted in the pdf file, seemingly at random. I looked at the HTML source, and could not see anything that obviously triggers the blank pages. For example, a web page that ought to print to about 35 pages generates a file of more than 600 pages, with most of them blank.

I can use Microsoft Edge as an alternative, but pdf files from that browser strip out all the color, and are nevertheless super huge, about ten times larger than the ones from Firefox. E.g. the file mentioned above, about 35 pages, would be about 1.3 MB from firefox, and 12 MB from Edge. So getting the file from Firefox would be nice.

Is there a reason why print to pdf is behaving in this strange way, and anything I can do about it?

No crash report, no trace, no anything. I click "Save [insert] as...", and Firefox hangs and stops responding. Windows automatically shuts it off when clicking. Launching Firefox again sometimes says there was a problem reloading the session, but that's not guaranteed.

I have 3 computers (2 desktops, 1 laptop). I want to permanently delete approx 300 unused/unneeded passwords. I deleted them from computer #1, then logged out of Firefox. The new count was 346 passwords.

I went to the second computer, deleted approx the same number from computer #2. The new count was 324 passwords I returned to computer # 1 and logged back into Firefox.

Within a short time, computer #1 is at 759 passwords, and computer 2 is at 691 passwords.

How do I get the deletions to be permanent? It's the second pass at doing this and I'm FRUSTRATED.

I'm experiencing a problem when I visit certain websites, like 'https://mui.com/x/react-data-grid/'. Every time I try to access this site, the page starts an infinite reloading loop, preventing me from using the website normally.

"Your browser is managed by your organization" suddenly appeared OS:Win11 Certificates: "ImportEnterpriseRoots" I've tried: Reinstalling Firefox Installing Firefox Developer Edition (it disapeared for few days but it was back) Deleting the registry key for it (after restart it appeared again)

 I have Avast and Malwarebytes but this has never happened to me before with this anti - virus

Attempting to log-in on Twitch with Firefox Browser - Developer version 122.0b9 (64-bit) is currently not possible, repeated messages are prompted by the Twitch website about "unsupported browser" and to contact browser support to resolve this issue.

Clearing cache, disabling extensions did not work. Using regular Firefox works without issues, only noticed this being an issue after most recent update for Firefox Dev browser.

Side effect as well since update is that any Cloudflare captcha is impossible and all website that use Cloudflare to "authenticate" that I'm human just outright fail or continue indefinitely.

I switched from windows 10 to 11 and to a new laptop. Here in my new laptop Asus tuf 15 ,even though it has better RAM , internet connection, cache memory, cores the FIREFOX doesnot function properly. It's extremly laggy specially when I use YOURUBE . In my earlier HP laptop with 8 GB ram I could use 10-15 tabs at one time .It would still not lag . It could do web development at the same time I could watch youtube tutorials. But now I barely open 4-5 tabs the youtube starts freezing up to the extent that I really get frustrated. Please so something or I will have to switch to BRAVE browser or something.

I change nothing in my settings and I am now on Dark background everywhere despite having: - forced the system settings (OS) to stay in light background - in about:preferences appearance I've manually selected (forced) the light background - in about:config I've tried to switch the browser.theme.content-theme to "1" (instead of "0")

this is really frustrating, I would like to get a better "reading" of what happens, as an Engineer I am happy to also squint at logs if needed, please consider adding a preference / settings change log file

When you add a new bookmark to a folder it's added at the end of the existing list.

Is there a way to make Firefox add it at the top of the list, instead?

I found an old answer, but, sadly, the extension granting my wish is no longer.

Also, I already know about sorting, but it's not what I need, because I'm doing a lot of manual bookmarks reordering and sorting will nullify it.

Thank you :)

Hi. I can't access my add-ons that I installed. When I click on the extensions icon it doesn't open that little menu like it does for other people, but it takes me to 'about:addons' in a new tab. I also want to pin my addons to my toolbar which is also not working. Please help me out

Today when I close many tabs using control w firefox seems to randomly jump around when choosing which next tab to close

I wish to have firefox always close the adjacent tab to the tab I just closed

This should be the default behavior ... I do not see any setting for this ... is there an addon to do this ?

I am using the latest firefox on ubuntu

• • • UPDATE*** below answer for setting `browser.tabs.selectOwnerOnClose` has no impact on this

I have had this problem for a while. I am not sure what to do so that I can fix this. Whenever I open a pdf or any application that can be opened in the browsers shows me two options for firefox browser. I attached a picture that will make it obvious what the problem is.

Hey folks, I use the firefox developer edition and I downloaded a zip file in it's private and when the download was complete I closed the window and open the download folder but the file was not there I haven't change the downloads folder location
