Firefox supportforum

Suddenly, most videos won't play. Upon closer inspection of the console messages, I get the following: "Cannot play media. No decoders for requested formats: video/mp4; codecs="avc1.42E01E mp4a.40.2", video/mp4; codecs="avc1.42E01E mp4a.40.2", video/mp4; codecs="avc1.42E01E mp4a.40.2", application/x-mpegurl, video/mp4; codecs="avc1.42E01E mp4a.40.2", application/x-mpegurl"

Only on Firefox, I can play mp4 videos normally in other browsers and media players. Tried reinstalling Firefox, refreshing, restarting the browser and the computer... My about:config media.mp4.enabled is set as "TRUE".

Other messages from the console:

"[warn][id_playback] id playback error: Object { code: "DNS", description: "Device not supported", reportAs: "INFO", internalError: true } player.min.js:1:55026 [error][player_error] <empty string> Object { description: "Device not supported""

Also tried disabling hardware acceleration and restarting the browser.

I'm clueless!

And suddenly.. there was Google translate asking me to translate a certain website. For the life f me (and I googled myself silly) I CANNOT get it to stop. even when I tell it I do not need it.

I've tried every trick I could find, yet to no avail.

I've NOT installed any add ons that would enable this. And it only happens with one website (hannants.co.uk) and no other (as far as I can see now). This is really ticking me off.

Like I said I googled to no avail and no extension within Firefox that I can see that are enabling. Can any one please help me is turning this piece of crap translation off?

Thanks

Can anyone tell me how to fix this?

After your latest update you broke the bookmark star function. This is key to my role in my job and if it is not fixed in a reasonable amount of time then I will have to switch back to Chrome. The instructions say to right click the 3 dots but it does not offer up anything when done. Add to address bar is the only thing that shows up when you do right click on the 3 dots instead of add to address bar like the article says. Please fix this ASAP!!!!

MAC's Mac is left on overnight. Come morning, MAC has lost power due to bad UPS I rebuild bookmarks and Add Ons. . Power up, & Rebooted and Firefox comes back as a new install with no bookmarks and no ADD ONs.

This has happened several times.

Suggestions????

My visual impairment means I have to run FireFox (and my computer) in dark mode. When I try to print, while it does not waste ink by printing the entire page black, where the text is the printed page only has black bars. An image of a print preview screen is attached. If there are settings to fix this there, I cannot see them because this does NOT use the dark mode and I can't see it.

Currently to print something, I take a screen shot and use another program to reverse the colors. I would like to not have to spend 30-40 min editing an image every time I want to print.

"Secure Connection Not Available,but not true" I have seen this question asked already, but NO reply. Does anyone ever reply to questions.? I have submitted numerous questions in the past without any reply.

Can you tell me what the above statement means?

Thank you for any help you are able to provide

I have been having problems with my sign-in on a particular web site lately. I have been in contact with them and finally found the problem. Firefox will not allow me to fully log in to my XXXXXX account. It will only allow me to get to the "Security Challenge" page then stops. I assume that it is because of some pop-up problem. Can someone please help?

Firefox is working fine, except it won't load gmail, and gmail works fine in other browsers. I get a tab crash message but no opportunity to submit a report. I copied and pasted the url of the working page from another browser and as before it just crashed while loading.

I have tried clearing history, refreshing firefox without add ons etc., and running a scan for malware.

None of this worked. Any suggestions appreciated.

Clicking on a link opens in a new tab (which it should) but then nothing happens in that tab. Right clicking on the link and choosing open in a new tab works just fine.

A downloaded file (VMware-workstation-full-16.1.0-17198959.exe), Dwnlded on 19/Mar/21, ended up with a file size of 0 KB (SEE Image $20210320-mar~1-Download_Final_File_Size=0KB.jpg).

The file size should have been 622 MB (SEE Image $20210320-mar~2-Download_Save-File_Size.jpg).

I was wondering if the file ending in ".exe.part" may have been mistakenly accepted as the real file & renamed to ".exe".

i'm using windows 10 and i have a firefox theme i like installed and in use, but when i open bookmarks, it doesn't show the theme and it's just looking so old, like windows xp? how can i change that? by the way i was using linux until yesterday.

I just switched back to Firefox and found that now when you download a file, you have to click on the little arrow next to the status bar to see the downloaded files.

I much prefer the way Chrome handles this. Whenever you download a file, it automatically shows a bar at the bottom of the screen showing the file progress, so you can immediately take actions like cancelling, or navigating to the file directory.

Is it possible to have Firefox display the downloads window automatically whenever you download a file?

Thanks! -Alterius

The Bookmarks are all there, but the url is missing. None of the extensions (including ones I've paid for are there)

The logins weren't there, but are now restored from a previous install.

What I have done...

1. exported bookmarks to html and checked them out there. They were broken there as well.

2. Refreshed Firefox,

3. Restarted the PC.

4. Uninstalled Firefox (and discovered that I had both X32 and X64 on my machine) - uninstalled both. 5. Reinstalled Firefox x64 (current version 86.0.1)

6. the places.sqlite files from previous restores have the same problem.

I've started to refresh the links for the toolbar which has taken me awhile. I don't want to have to do it for all my hundred's of bookmarks.

Ideally what I'd like to do is uninstall the latest update, look at the bookmarks to see if they are still stuffed, and if the extensions are there. If they are ok, then I want to back the bookmarks to html. Reinstall the update, then restore the bookmarks. (And make a list of the extension names so I can reinstall them).

My guess is either that the sqlite file has corrupted, or the update has changed the file layout for the bookmarks, etc, and it's unable to interpret the links.

When Firefox upgraded the browser a few days ago, I lost the google email "pclaincz@gmail.com. My other google email is fine. (plaincz2437@gmail.com). I tried to recover it but the original password is not "valid." Any help I could get to recover this second email would be appreciated.

Last Firefox refresh saved all my working tabs, but lost my Toolbar, ALL bookmarks, and ALL saved Logins with passwords.

WTF?

I attempted to import my last saved version from a profile folder (I wasn't born yesterday), but nothing happens. Why can't I import? MS Edge conveniently has them all, but I don't like its layout and lack of menu bar, which I use a lot.

I've been screwed a few times by Firefox updates and refreshes. Why does this happen?

Please recommend a solution.

Well I've been looking into this a lot, but at this point I'm just spinning in circles.

Only when watching youtube streams, they'll cut out rather often. The stats for nerds has the Network Activity drop to 0, and live latency shoots up. Its only in firefox.

I can have the same stream open in chrome/edge, and they are not usually lagging when firefox does, or when they do it's for a shorter period.

I have tried safemode, turning off protections on Youtube, clearing cache, telling firefox to not use any proxies, changing my DNS, running the HTTP logging tool.

The logging tool looks like it could be the socket timing out, but I'm unsure how to fix it.

Is this just an issue with youtube hating firefox, or is it something I could fix?
