Hello, I have a problem with firefox and it's recently unable to open Google and Youtube due to HTTP Strict Transport Security (HSTS) with an error Code : SEC_ERROR_UNKNOWN_ISSUER

I have done the steps in here : https://support.mozilla.org/en-US/kb/error-codes-secure-websites I don't have any third-party Antivirus

I have also do about:config security.enterprise_roots.enabled by changing to true. It works but unfortunately youtube is broken when i set it to true.

I can't also accept the risk and continue since there's no button that says it.

Thank you

My installation of 32-bit Firefox 102 had been repeatedly crashing, sometimes for no apparent reason. I decided to download the 64-bit version of Firefox 102, uninstalled the 32-bit version, carried out a standard installed and all this appeared successful. I noticed that I was getting a lot of advertisements and remembered that I had had Ghostery installed as an extension in my 32-bit Firefox. I went to the extensions page, selected Ghostery and asked for it to be added. Shortly after that, I got a message that the installation had been aborted because the extension might be corrupt. I tried again and got the same message. I tried another ad blocker, and got the same message with that one; and tried a third with the same result. What is going on? I haven't changed any settings in Firefox since the standard installation, and the extensions were from the Firefox source, so how can the extensions be corrupt? If it isn't corrupt, why isn't Firefox installing it?

Hello,

I'm using Firefox 102.0 (64-bit) on Win 10. When I click on the download icon of email attachments or Whatsapp files, firefox opens the pdf files in a new tab instead of downloading them. All other file formats are downloaded correctly instead. How can I correct this problem, please?

I've been noticing this more and more recently. I'm using Firefox 102.0 on a Mac running Monterey (12.4) with 64GB RAM. Firefox will suddenly zoom up on a screen between 400% up to 800% (I'm guessing; no way to verify this): see screenshot. This happens on random pages without my hitting any keys or clicking on anything, and I cannot replicate it. Note that I do not have screen zoom engaged, nor do I have any sort of zoom mechanism turned on in the OS. Hitting "undo" does nothing, as the browser thinks I'm trying to undo an action on the page, not a zoom. Resetting Firefox or restarting makes no difference.

Note that the screenshot is at actual size, but I have no way to control the resolution at which it shows up for you.

Whenever I try to full screen a video the first time I open the browser, the video will not completely fill the screen. It only happens on firefox and the first time I open the browser. I thought it was my extensions but it was not that. A thread was created on reddit describing the problem I have. I have linked it here. https://www.reddit.com/r/firefox/comments/rhwuvz/firefox_full_screen_on_win11_always_leaves_some/ I tried to change themes and that also did not work. Not sure what the problem is. Please help.

My OS is Pop! OS. Using 'Tidal' as a web based music streaming service and I play vids on YouTube. Every time a new song or video starts, or when I skip, rewind or do anything like that, it auto resets the volume level output in my sound settings to about 75 to 80 % of the max possible level. So basically, I have to adjust each and every new song by hand, it is infuriating. I block facebooknet in Umatrix and firebaseinstallation googleapis as well as google tag manager but nothing else. That's on Tidal, similarly I do not block essential cookies on YouTube, so I don't think that is the problem. I have a hunch that the answer is somewhere in about:config. If this is intentional, then I'm giving up hope. Thank you.

Hi, this is a minor problem and more a quality-of-life thing, as there is no hard crash or bug per se. Context: I need to print a LOT of things every month for the job, so I download a LOT of PDFs.

Problem: When downloading a PDF, if I open it via the dropdown menu in the menubar, it opens, but immediately unfocuses Firefox. That's it. Why the unfocusing? Lol.

Limits: If I mark PDFs to open automatically (in the options) instead of downloading, then it opens fine and no loss of focus. Same thing if I open from a folder, it's set to open in Firefox and it does so, with no loss of focus. As far as I can tell, the issue appears only when opening from the download button/icon/dropdown menu from the menubar.

Suggestion 1) Adding a "Download AND Open in Firefox" option in the settings would be my ultimate greatest option but.... maybe not the best for cluttering millions of people's browser options. It's just what "I" want to do ;)

Suggestion 2) Trace where it loses focus and re-focus / prevent loss of focus when opening from the menu.

Hi everybody, I never cleared my browsing history so far, because I often need to know which websites I already visited when I perform a research on Google. Having the previously visited URLs shown in a different colour is useful for my work.

However, I am wondering whether this huge amount of data could affect the browser speed and memory usage. More specifically, I have a few questions:

1) Out of curiosity, in which file of Firefox installation folder the history is saved, and where can I find it? 2) Do you think it is possible to clear ALL the browsing history, except for one specific URL? 3) Could a cluttered browsing history file affect negatively my browser performance?

Many thanks in advance for your help, Elisa

It's June 2022, and I am using FF64 101.0.1.

My issue is best described by Zaayl (2017) at https://support.mozilla.org/en-US/questions/1157490, but the working and easiest solution I found was the one offered by delclemons (2018) at https://support.mozilla.org/en-US/questions/1229621#question-reply.

My starting page is blank. I have an extension that shows my external IP as a country flag when FF starts up. If the flag doesn't show, I know I still cannot connect to any site. Similar to Zaayl's case, my FF can be able to connect to sites only after a certain amount of time, which varies from instant - very rarely - up to over 10 minutes. The wait always gets longer, especially when FF crashes and have to restart.

I've been searching a long, long time for the right fix. I cringe at the idea that I have to reinstall FF every time there's a major issue, like this one. Syncing back bookmarks and passwords and reinstalling the extensions are the easy part. The painful part is having to set details of accounts in the containers afterwards. I am so glad that is over now. Connection to sites is no longer prolonged after FF startup.

I wanted to thank the persons concerned, but I couldn't reply to their messages, which are now archived. So, I decided to post a new one here to do that; also, to help users who have to same issue as mine.

I set FireFox to automatically save PDF links. Also I disabled the annoying downloads pop-up. When I click on a link, though, the screen briefly flashes white. The cursor stays in-place, so I can work under this condition, but it's an annoying distraction. Especially since nothing is being opened, so I'd expect the FireFox view to just stay as-is.

I've seen postings complaining about their blackscreen-themes flashing white when they do this. If I read right, the posted solutions were just to flash black instead of white. That's not what I'm trying to do here, I want to suppress the flash.

I'm not sure what is causing this, but it started at least a few months ago. I will be using firefox, and anywhere between a few minutes, or a few days, it will suddenly stop loading anything and I will have to completely quit it and restart it to get anything working again. No, it is not the HTTP3 problem; that was the first thing I tried. I've also uninstalled, and reinstalled the entire program, clearing all settings, etc. I am on windows. Generally good on firefox updates, will check and update usually every week or two.

Funny thing is, I also installed firefox nightly and that does not have this problem (although I have not used it as extensively as I normally do when browsing, so maybe I didn't hit whatever triggers this issue). It also works properly on other computers (as far as I'm aware). So I still think something is corrupt or wrong with my normal firefox program. I just don't know what or how.
