Firefox Support Forum

Problem/possibly relevant info:

• yesterday evening, auto-fill for logins/passwords was working
• when I opened my laptop (from standby) this morning, my welcome screen was frozen at last night's day/time when I lowered the lid so I restarted (press and hold power button; this happens all the time as of the past 6 months or so)
• logins/passwords have now disappeared
• Windows 10, Firefox v.102.0 (updated July 1st)

After 2 hours of trying to find answers, I've done/discovered the following:

• followed steps here: https://lifehacker.com/how-to-recover-your-missing-firefox-passwords-1835616191 -- didn't work
• I don't have other profiles and am not synced to another device
• I've had no luck finding an "Old Firefox" folder
• logins.json, logins.json-2.corrupt, and logins-backup.json all have the same timestamp (this morning) and file size
• when I open logins.json and logins-back-up.json in Firefox, I get the following message: SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data (I suspect this is where I'm in big trouble...)

I am very non-techy so any straightforward suggestions would be greatly appreciated. Otherwise, I guess I'll have to decide if I want to pay to get it fixed or go to the hassle of re-setting all my passwords. ;)

Thanks!

Since latest version update of Fire Fox, I'm unable to sign into OUTLOOK. I get to the Sign-in Screen, but when I toggle to enter password, page starts to reload login name/password, but page never loads. Tried multiple times in Fire Fox, but launching MS - EDGE I can get logged in and going immediately. Please advise.

Here's where it gets stalled:

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.

I have found that my Fiefox cannot handle live news streaming and video playback and the picture freezes but the sound continues. This has been going on for years but I do not have a problem with any other browser.

How do I restore the display of this vital information? Why was it removed in the first place???

Edit: This is at least the case for downloads where the conclusion results in the file being opened, instead of saved: https://cdn.discordapp.com/attachments/628080126630035466/993530387601043557/unknown.png

In the last couple of days I cannot log into Twitter in Firefox. I get a message that something is wrong "but don't fret, it is not your fault". When I hit Refresh, it works, but only once. What is wrong? I have the latest Firefox version. Thanks

Whenever I try to open google or search anything, It shows this error and only button to Go Back

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection. What can you do about it?

www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

Someone could be trying to impersonate the site and you should not continue.

Websites prove their identity via certificates. Firefox does not trust www.google.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

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

Couldn't open Firefox XPCOM error.

Downloaded Firefox again and I now have Firefox in OS/Program Files/Mozilla Firefox (which doesn't work - XPCOM error) and a second version in OS/Program Files (x86) which works but has lost all my bookmarks and passwords.

How can I fix this please.

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?

Other than what i described above, i have submitted questions, and now FF is blinking ! This is a very unstable release!. Mozilla needs to retract this crap and work on a real browser update. I was prompted to update to 102, then after experiencing tons of problems, another update, to 102.1, which achieved....nothing at all.

What is going on with mozilla? this is crazy!

I suddenly can't click the "copy song link" item in Spotify anymore. It worked fine last week and works normally in Chrome.

It also fails in Troubleshoot Mode and after clearing Startup Cache.

Firefox 102.0 (64 bit) on Windows 10

See dialog box screen print below. The .cpp file is not a GIT file. A .cpp file is a C++ program source file from Microsoft Visual Studio, and I should be able to open the file with Visual Studio 2019 (current version of Visual Studio on my PC). But misclassifying the .ccp file as GIT does not give me the option of opening the file with Visual Studio 2019. How do I change the classification of .cpp files from GIT to C++ (I'm on the newest version of Firefox...all prior versions worked correctly) ?

Hi, I've just reinstalled my firefox browser and I have some issues: - I can't install ANY add-on, even the ones from Mozilla Firefox itself, I get the message "Installation aborted because the add-on appears to be corrupt." on all of them - I can't add another language on my browser and get an error message "Firefox can't update your languages right now" - The screenshot option doesn't work, on any page

I have already tried deleting and removing all data from Firefox, and reinstalling it again but it doesn't work. I'm really at a loss with what to do.

Thanks

I updated to version 102 and found that all my passwords/logins have disappeared with that. I'm always connected with my account which is active on various devices.

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.

Solutions tried but unsuccessful: 1. Checked page size. It is correct at (80 x 297mm) 2. Cleared browsing history, cache, site settings, etc from start of time. 3. I have put print_resolution to 0 in about:config 4. I have put scaling to 1 in about:config ([https://support.mozilla.org/en-US/que.../1297631]) 5. I have put shrink to true in about:config ([https://support.mozilla.org/en-US/que.../1297631]) 6. I have alternated values (1 and 9) of paper_data in about:config (https://support.mozilla.org/en-US/questions/1297631) 7. Uninstalled ticket printer driver, rebooted PC and then installed again (Xprinter XP-80C). 8. Uninstalled Firefox completely, rebooted PC and downloaded again from Firefox website. 9. I have tested on a Laser A4 printer from Firefox on that same PC. Works fine. 10. Attached is the scanned picture of print from Firefox 100. Firefox 100 11. Another attached contains the scanned picture of print (correct one!) when I re-installed Firefox 64 link text

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.
