Firefox Community Forum

Up until a few weeks ago, I could see and access Mobile Bookmarks (I sync these to my Firefox Desktop) using the Firefox Desktop browser from the Bookmarks drop-down menu in the topmost toolbar.

Now, I can no longer find Mobile Bookmarks in the Bookmarks drop-down menu.

I can still find it by choosing Manage Bookmarks and, in the resulting pop-up, I can see it in its regular location there. However, this is significantly less convenient as it requires me to juggle another window and perform more clicks.

Is it missing due to a bug? Does Mozilla intend to fix/address this?

Thank you in advance for any help.

I seem to have a problem with Firefox's builtin PDF viewer. Instead of black text on a white or gray background or something else sensible, I get black text floating over my desktop background in the part of the Firefox window that's showing a PDF. PDFs display fine in an external viewer, but that's just passing the buck, isn't it? Is there a way to fix this on Firefox?

I suspect hardware acceleration is the issue, but everything else seems fine, so I don't want to just blanket disable hardware acceleration. How can acceleration for PDFs alone be disabled?

As I said in the title, the spellchecker add-on I use, LanguageTool, does not work on this site. I am not fine with that. What's the best way to get it working here? Any answers that amount to "you don't" are not acceptable.

I need to uninsntall my present version of firefox and reinstall an upgraded version . i have a desktop frontier has ended their e-mail and therefore I no longer have the e-mail that everyone knows me by I have no e-mail except on my phone. My reachaable E-Mail is marcumgrover@gmail.com

I have used firefox for quiet many years now, but recently after the update, it i sucking in a lot of resources, I am not sure what the problem is but the cpu engagement of all the 4 cores are getting to 50 percent and longer uses are making it go as high as 95 percent. So, I have already done the following,

• Previously I thought it to be snap issue, so I changed to deb but that also didn't changed much.
• Then I thought it to be some other issue and tried to fix few log issues of ubuntu which I think were unrelated to the problem.
• The system is running so hot that one can't put his hand on it for long.
• Ultimately I switched to fedora, and everything came to normal. The firefox then was of version 123 or 125(or 126, but it was 2-3 versions back, you may find it with what version fedora ships with but I remember it to be significantly lesser than 129).
• I use 3-4 windows at a time with 6-10 tabs open(but mostly pdfs). The firefox was working all fine with no temperature and resource issues, then I remembered to do update, and soon as firefox is upgraded to 129. It has started to cause the same issue, it is damaging the hardware, the hissing sound and temperature increase have come back.

The outcome is that I have came to know that there is some problem in either the upgrade process or the new version. THIS IS HIGHLY DISAPPOINTING. Please provided instructions on how to fix it, or should I open a issue in bugzilla, I can not understand what is the problem? please ask for an other information if required.

Hello guys, as in title - I use custom NextDNS set of rules on DNS-over-HTTPS. As of today, Firefox can't connect to the provider. AFAIK Troubleshoot Mode is also affected. The other devices using NextDNS on my network work just fine and when I set the DNS to work system-wide as a kind of workaround, I don't get an issue. Same when I use other DNS-over-HTTPS options in the Firefox Preferences. Yesterday the problem didn't occur and I haven't performed any updates since yesterday - both Firefox and NetworkManager seem to be up to date.

Additional info: OS: EndeavourOS (Arch Linux) Firefox version: 129.0.2

If any other info is needed, I'll be happy to provide it to you.

I mistakenly dragged a text from a search box and dropped it on my browser page. If this text is a url (Ex: www.some_site.com), Firefox will navigate to that page. How do I prevent Firefox from opening dropped links on pages?

For languages that don't put spaces between words there's a Unicode character zero-width space - ​ aka ​ - that a browser is supposed to use as a cue to break a line. Firefox ignores it.

Hi, I try to visit my website ahsapsaksi.com. When I visit on firefox(Desktop and ios). I see the isimtescil template which is the old version of the website. However when I access from another browser like opera I see the updated website(welcome to acme page) only with VPN connection. I tried to delete cookies, visited in private tab etc., however I couldn't manage to see my updated website in firefox(in both desktop and ios).

Can you help me please?

Now a new update. When I visit the website on firefox with VPN connection, I saw the updated version, and from now on I cannot see the website without the VPN at all. I dont understand what is going on. But I tried to clear that cookie many times. Now it looks like the cookie is deleted not by deleting in the settings but using VPN. Now the problem is I cannot visit the website without VPN. Can you explain my experience? why did it happen?

Hi,

on X11 it does not seem to be possible to copy gifs from firefox.

When copying a gif the "TARGETS" conversion only gives the following atoms:

   TIMESTAMP
   TARGETS
   MULTIPLE
   SAVE_TARGETS
   text/html
   text/_moz_htmlinfo
   text/_moz_htmlcontext
   image/png
   image/bmp
   image/x-bmp
   image/x-MS-bmp
   image/x-icon
   image/x-ico
   image/x-win-bitmap
   image/vnd.microsoft.icon
   application/ico
   image/ico
   image/icon
   text/ico
   image/jpeg
   image/tiff
   image/avif
   image/jxl

When trying to convert to "image/gif" the conversion fails. (I am requesting conversion from the CLIPBOARD atom)

I am running Firefox 129.0.2 (64-bit) on Ubuntu 20.04.4

Recently, I have been browsing a StackExchange site and hit the back button of the browser several times (still remaining on StackExchange). I then realized that upon the last button click, Firefox downloaded a weird HTML file called something like ha71ksd.htm. The file was empty (0KB) and when uploading it to VirusTotal it showed me a completely different file there (probably since the hash of an empty file is always the same).

In any case, I am a bit worried that I might have been infected by a virus. Therefore, I'd like to at least reproduce what happened. I read in different places that it might have something to do with a wrong MIME type reported by a server prompting Firefox to download instead of displaying a file. But Stackoverflow having such a misconfiguration is also strange. I know that a 0KB file cannot contain anything malicious but the whole incident seemed highly suspicious and I need to find out what happened.

Any help or tips are appreciated!

My situation is similar to:

https://support.mozilla.org/en-US/questions/1410815

but that thread is archived.

Problem: I opened the Downloads folder and meant to click 'Organize' but I accidentally clicked 'Clear Downloads'. All the names in the Downloads list are now gone and I want to bring them back.

Situation: I did not want to clear the Downloads list, all I wanted to do was learn what options were listed in the 'Organize' button. I was hoping there might be an option to have past Downloads (the names on the Downloads list, not the downloaded files themselves) sorted by date and by domain. But now all the names in the Downloads list are gone. I don't want this to happen again so what's the best solution for this problem?

cor-el says (in page linked above) that a backup of 'places.sqlite' can recover the Downloads list. I copied that file to my Desktop but I'm guessing that it's too late for this file to be of any use now, as I did this only *after* the Downloads list was cleared.

The information I've read about the places.sqlite file (https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional , https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data , and https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile#w_bookmarks-downloads-and-browsing-history) seems to focus mainly on its relation to Bookmarks, not Downloads. Does everything that article say about restoring Bookmarks also apply to restoring Downloads?

I haven't made a backup before in Firefox specifially but my system (Linux) took a system snapshot (Timeshift) before this mistake happened. Would reverting the system to the previous snapshot allow me to access the old places.sqlite-wal file that has the now-missing Downloads list?

Also, is there a way to customize the appearance of Downloads window? I'd like to add some space between the 'Organize' button and the 'Clear Downloads' button. If I could have them separated just a little bit more, I think it might help to prevent this kind of thing from happening again.

In the meantime, I'm thinking of writing a script that regularly backs up the places.sqlite-wal file so that if this happens again, I can just use the backup. But as of now I'm uncertain that it will do what I need it to do.

Any help is appreciated. I hope I've provided enough information to make this report clear. If any needed info is missing, please let me know.

Thank you.

I have had this CPU for 8 months. I have had issues from day 1 with the stock Fedora install of Firefox where text is missing and some green and/or pink boxes appear where the text boxes should be. This has happened with all versions up to 129.0.

This has only been happening with Firefox. Vscodium, (chrome based) Brave and every other Wayland application including foot and freecad render correctly. it is only firefox and only firefox with this GPU. If I run Firefox under qemu without eGL then the rendering is good. If I run it under qemu and enable the virtioGL driver I get the same issue.

I attach a sample of a screen shot that shows that was captured from the frame buffer. In the bottom left corner, you can see quite a few characters missing. This happens randomly and sometimes goes away when scrolling.

I have seen other issues that say that it is a hardware problem, but I am not convinced. This happened with mesa-24.2.0. Find the glewinfo attached below: (Glewinfo log is very long, uploaded to Pastebin for better viewing) https://pastebin.com/raw/1NMnAjmc
