I'm using Firefox 76 packaged with fedora 30 but it wont display a video (weirdly youtube does work). I'm getting the message: "this content requires adobe flash or HTML5 video support..." I don't want to install flash because I've seen some content somewhere about security concerns. I looked for an extension or add-on but none of them seem to be Mozilla approved and most of them don't seem to address this issue anyway. I can't find a setting to fix this in Firefox. I've seen an archived thread about this problem suggesting maybe some linux library issue, but it contained no solution. Maybe I'm missing something fundamental but it's 2021 now and I'd like my Firefox to support a bit of video here and there other than youtube. Has anyone got a solution?

My OS got updated to Gnome 40.3 after that the configuration got mess up, when checking the about:support page the page was blank so I refreshed Firefox. After that the problem persist so I erased the "places.sqlite" and "favicons.sqlite" as instructed in the troubleshoot page but then I got the following problem and uninstalling, erasing the program files and reinstalling Firefox in the OS didn't solve it

    Hi all,

    i'm currently developing an add-on that has an import from file feature that needs to open an "Open file" dialog, now the problem is that in order to do that i had to do the following:

    • inject some javascript code in the active page as a content script
    • call the execute command from the extension to open the dialog popup (that is actually emulating a click)

    I have to do it, because from an extension when a "File open" dialog appear, the extension lose the focus and it is automatically closed, and its context destroyed, so when i actually press open on the dialog, the "caller" is already gone (https://stackoverflow.com/questions/26884140/open-import-file-in-a-chrome-extension/26917671#26917671 you can refer to my stackoverflow question to get an idea of what i was doing)

    This works fine in chrome (And it worked for a while on firefox) but probably in the latest months/years (not sure when it happened) it stopped working and when i press the import button nothing happens, after some investigation i found what is the problem: the "block popup" windows option enabled by default (i suppose it is enabled by default i don't remember to have never enabled it), so when i disable it, the feature resume working. What i'm wondering is if there is a way to programmatically add an exception to the popup blocker option while installing the extension, or if there is any way to avoid closing the exception popup when the "File Open" Dialog appears.

    Thanks everyone

    1. Search bar doesn't work for search. If i type anything, i.e. "firefox", it opens firefox.com 2. Settings > Search reveals that I have no search engines, and nothing is selected as a default search engine. 3. "Restore default search engines" does nothing 4. Removing all files related to word "search" in root directory does nothing, still has no search engines after restart. 5. Switching to new profile does work, default search engines appear and search bar is working fine. 6. As soon as I sign in my account and sync starts, profile loses all search engines and search bar stops working.

    I believe my firefox sync account is syncing 0 search engines to my browser, and I can't add new search engines. I have Manjaro Linux and a Windows machine, both with firefox but using different versions. Both browsers lost all search engines after sync.

    Hello,

    I updated firefox and it's now hard to tell when one tab ends and another begins when you have multiple inactive tabs next to each other, which is a major annoyance.

    The way to solve this would be to have the inactive tabs have a border around them like the active tab, have them have a different background color from the toolbar, or otherwise have some kind of separator between them. I saw another answer that gave a temporary solution, but the same answer said the solution was going to stop working in a future update. Is there a permanent solution?

    Hello,

    At first I thought it was a tired Arch Manjaro install that was perhaps the issue. Now that I've done fresh installs of Arch (Manjaro & Arco), Ubuntu (KDE, Gnome, & XFCE) on both my workstation and laptop, I can say it's not my Hardware or OS. So why is Firefox crashing all the time? Mid chat conversations, etc. Again, fresh OS install and zero Add-Ons installed. I can't use Firefox, even if I badly wanted too when it tanks on me all the time.

    Problem with printing at reduced scale, did not notice it before a few days ago so could have been after a recent update. Am now using Firefox 90.0 for Linux Mint 19.3. Printing to US Letter size (which had been broken with "na_letter" being stuffed in to the config at one point, but I switched it back to "US Letter" and then it started working again a few months ago - Thank you).

    I see some similar questions listed, so this may be simply adding information to something known:

    Printing with "Fit to page fit" works fine, with correct preview. Print with scale set to 100% works fine, with correct preview.

    Printing with scale set to less than 100% (say 70% or 80%) showed in the preview the page rescaled as expected. The actual printed output is also rescaled as expected, but the page size gets cropped at the right and bottom by what appears to be the same percentage, ending up with lost content. The bit that does print seems to match what is shown in the print preview perfectly, suggesting it would have been totally perfect if the print area had not been cropped along with reducing the text and image sizes.

    I tried the "Print using the system dialogue" option, and the printed result had the same pathology.

    Same problem also happens when I print to PDF. For this I tried doing the same thing twice, both scaled at 70%, and on comparing found that the preview in firefox had also become cropped a bit but not to the same extent. I did not notice any cropping for the first print to PDF, but now seem unable to get back to what I saw originally in the preview, with correct resizing and no cropping. Playing around some more with printing at 100% vs 70% vs 80% to "fit to page width", I seem to be getting changing crops happening each time in the preview for the reduced sizes.

    But the preview and print are both still correct for 100% scaling and for "fit to page width".

    Sample web page I used here was https://getpocket.com/explore/item/a-shoulder-workout-for-better-posture?utm_source=pocket-newtab The screen shot shows the preview after the first reduced print to PDF, with no settings changed. The little bit of side cropping seen in the preview did not happen when I did the first print to PDF.

    I have encountered one web site that has several pages that display as graphics instead of text. I have visited this site before several months ago and the display was accurate then. The first image is how it looks now. The second image is how it looked several months ago. I am running Ubuntu 20.04.2 and Firefox 89.0.2. It's very strange that this is the only page that displays this way. I checked the page in Chromium and it displays correctly in that browser. Is this Firefox or quirky html?

    Since I upgraded to Firefox 90.0, my RSS feeds can not longer be refreshed in my feed reader. I get a 403 error ("access denied"). When I check the debug information on the URL, it says:

    I am using Feedbro on Firefox 90 on Ubuntu 20.04 on two different computers, and getting same problem.

    Clearing the cache, trying other feed readers, deleting cookies etc do not help.

    A sample feed URL: https://news.google.com/rss/search?hl=en-US&gl=US&q=mozilla&ceid=US:en In Firefox, I can open a tab and see the text file. But Feedbro, or any other reader, cannot detect the feeds on this page any more.

    Any advice? I absolutely rely on RSS feeds for my work.

    After the last update to version 90.0, I can't continue to use firefox browser. The problem is about opening google sites (youtube, gmail). Other websites seems to work normal, but I can't open youtube and gmail now (google.com itself works heavily). When I type url and click enter, it takes so much time to load, often not loading the site or partially load. Other browsers installed on the same system works normally with the "problematic" websites. I tried hard reload (ctrl+f5), cleaning all browser data, and uninstalling and reinstalling. None of the mentioned actions helped. Please help me to identify and solve the issue.
