Diễn đàn hỗ trợ Firefox

Hi, I am seeking a job and had a number of important tabs open when I had to restart my browser. Unfortunately, it was set to clear history on restart. Is there any way, on a windows10 pc, to recover them? Are they stored anywhere?

We use Firefox as our company default and it has been running fine. This morning our devices started updating to version 82.0 and now it will not re-open. We get the following in event viewer:

Faulting application name: firefox.exe, version: 82.0.0.7592, time stamp: 0x5f8738dd Faulting module name: ntdll.dll, version: 10.0.18362.1049, time stamp: 0xb5beef21 Exception code: 0xc0000409 Fault offset: 0x00000000000a1170 Faulting process id: 0x504 Faulting application start time: 0x01d6a79d51cff95a Faulting application path: C:\Program Files\Mozilla Firefox\firefox.exe Faulting module path: C:\WINDOWS\SYSTEM32\ntdll.dll Report Id: a6b172b9-a2b5-4bc0-a874-22a48b48aa06 Faulting package full name: Faulting package-relative application ID:

When trying to uninstall from Program and Features we get the following NSIS error (attached).

Hello,

I'm not sure when it started, maybe a week ago. When I open firefox, I'm logged out of "most" of my accounts sometimes. I'll log back in and it will last a few browser closing and reopenings. Some websites seem to log out quicker, or it's possibly just random.

I've been using Firefox for a very long time and I've never had an issue like this. It's frustrating because I have to go through 2-factor each time a website logs me out. And so far, it hasn't happened to Discord in browser. It affects Gmail, Hotmail, Twitter, Facebook, and Reddit.

I did not change any settings recently until after it started happening (I set "Enhanced Tracking Protection" to standard thinking it would help but it hasn't).

Thank you.

My old PC died, luckily, I had a new (secondhand) one ready to go.

I am using a pre-quantum version of Firefox.

Where can I get legacy versions of extensions that I need?

Yes, they've all been updated and maintained, but, there are several whose functions are severaly depreciated - including one where I would now have to actually PAY MONEY to do what I used to be able to do with ease on the legacy version.

Urgently seeking legacy versions that all worked fine before my old PC hit the dust last week.

I reformated my pc. When i installed Firefox and tried to sync it asked for a code that was sent to my e-mail, but I can't access my e-mail. how can I recover my account if I can't access my e-mail? It's there any way to contact Firefox support to recover my account by other ways?

On FF v78.0.2 (Win 10/64-bit), it used to be that I could open PDF links within a website using FF's built-in PDF Viewer. However, after saving them to disk, when I opened the PDF from the Downloads panel, it would open in my preferred 3rd party app. This was desired and worked perfectly.

But this seems to have changed! I either have to commit to the built-in always, or an external app always, irrespective of whether I am opening from a browser link or the download panel.

This is a terrible behavior. FF should open PDFs in the download handler (like ALL other file types there) with the OS's preferred PDF handler, which, in my case, is not FF's built-in Viewer.

If open a PDF in the built-in Viewer and save it from there, why would I want to re-open it in the built-in PDF viewer when opening from the download panel?

FF's built-in Viewer is great for a quick view of a PDF, I quite like it. But if I take the time to save it, I typically want more advanced functionality, like highlighting, filling in forms, etc. It worked perfectly before, please revert and stop fixing things that aren't broken. Or at least differentiate between the download panel and website links. Is there any hope in submitting a bug report?

Viewing a national newspaper site today, Firefox popped up an odd message Continue to installation of Flash player. It then loads (tries) https://performintenselyquickapplication.icu and an ID string. I think I can run Flash already on my browser so why do I have to do this?

The URL worries me, it may be genuine but would like confirmation it is. As mentioned I can already see/use Flash so why the message?

Search for https://performintenselyquickapplication.icu returns nothing other than an Alexa position. Thanks in advance. McP/

Hello. I am having the same issue as another user, but they flagged their question as solved so I'm making a new one just in case.

I can't login properly to YouTube, only in Firefox, even after clearing cache and cookies and disabling add-ons/running safe mode. I can login to my Google account, view my playlists and recommended videos (although the main page with recommendations only shows 5 lines of videos and when scrolling further is not loading). I can't make any edits, for example add videos to the "Watch Later" playlist, that require a login. When I click login, Google shows the 405 error "The request method GET is inappropriate for the URL /youtubei/v1/browse/edit_playlist. That’s all we know." or with other URL, depending on the action taken.

What can I do? Thank you.

The firefox browser has been closing itself recently, quite often aswell(2 times a day minimum). No crash reports, nothing like that afterwards either. when i reopen the browser it continues where i left off. i use the duckdugo extention if that may play a role in it.

Any ideas?

All the best!

Hi, After an automatic update, the Firefox restore session feature stopped working. Here are the things I have tried to fix the problem: 1) Disable all the plugins and Extensions I had This did not help, so that can't be 2) I removed and reinstalled the latest version of Firefox, and that did not help either.

Any help you can provide will be much appreciated.

Thanks Carlos

Hello there! I want to add a few words to my dictionary spell check, and I've looked up many sites where everyone says I have to edit the persdict.dat in the Profiles folder. The only problem is the persdict.dat file doesn't exists on my end. And I can't find it anywhere on my system. NOWHERE. I've tried turning on Hidden Items, even searching it, no luck. All i have is the XPI files that count as dictionary files. Can someone please help me how to get the file? Thanks in advance

Please help me return to being able to print webpages from Firefox to a pdf.

I installed my cd copy of Adobe Standard X when I bought my Windows 10 Thinkpad in December, 2019. It printed webpages to pdf just fine until 4 days ago.

I've attached 4 screenshots:

1) The Firefox error message I now get when I try to print a webpage.

2) This may not be relevant, but this is the page I got saying the screenshot couldn't be saved as a pdf or Word Doc.

3) The printer list in my Windows 10 settings, showing pdf is the default. I don't know if all along Firefox was printing from the version of Adobe I installed or something that came on the laptop.

4) The error message when I experimented to see if I could print to a pdf in Chrome.

Adobe quit supporting Adobe Standard X years ago, so I don't think that's the issue. Oddly, this happened right around the time Microsoft withdrew support from Office 2010, but I can't guess how that might be involved.

Hi - Some of my bookmarks are missing their favicons (like Southwest Airlines, WalMart). I just get the generic globe favicon for them. I've tried deleting the bookmark, reloading, renaming, clearing the cache, etc., but nothing works. How do I get these favicons to appear?

I cannot figure out how to authorize Blue Mountain Cards to send greeting cards to people through Facebook. At one time I was able to do that, and it is very frustrating to no longer be able to do so. I have spent hours this morning trying to figure out a way.
