Firefox 技術支援討論區

Few days ago, some of our clients and few (not all) internal PC are get stucked on a PR_CONNECT_RESET_ERROR on our website. Only on 117 windows version (118 developer version and 119 nightly seems ok). We tried to repair firefox, it works on 95% but we can't ask our client to do this. It works on Chrome & Edge.

We running out of ideas : - we only accept TLS 1.2 / 1.3 - checking CSP - Both IIS and Apache are not working - Firewall are not blocking

Certain images are never created or loaded in my browser. Youtube thumbnails, for example, display as only light grey squares. I thought maybe my addons might be causing this, but the only one that seems capable is uBlock Origin, and I even disabled it completely. Anyone know what could cause this? Surely its a caching issue or something. I can include images if anyones curious.

TL;DR: Moved firefox browsers, didnt properly export passwords, uninstalled other browser, had logins.json from profile folder, needed to know how to import manually.

Fixed. I just installed the older browser, and properly exported the passwords this time.

I have several profiles. They all have the same Chrome folder contents, but only some of them have the "chrome_debugger_profile" folder.

I'm guessing I must have generated it along the way while tweaking the Chrome folder contents?

Firefox 117.0.1 (64 bit) Build 20230912013654 Windows 10 Home - Version 22H2 OS build 19045.3448 The link to download my Sears credit card statement in pdf form has disappeared when accessing the website (https://citiretailservices.citibankonline.com) with Firefox. It still appears and works normally when the website is accessed with Chrome. I have the uBlock Origin extension installed on Firefox, but it is disabled on the Sears website. Screencaps attached.

I have been having this issue for such a long time now but its really getting ridiculous now, I have tried to follow so many guides and re-installs and .XPI installs and nothing is working, I am beyond stumped as to what can be the problem, someone please help me fix this.

Which file/s contains only the browser settings, not including the extensions, which are transferable to other profiles? prefs.js? the contents of the settings folder?

Everything was working fine on Firefox up until a couple weeks ago when my searches started lagging.

What happens is - if I type a search into the main URL/search bar on the browser, it loads just fine. But if I type a 2nd search into a website search bar, such as on google.com, there is about a 12 second delay between me hitting enter and the page actually starting to load. The page freezes during this time and is unable to be interacted with. This issue does not happen in any other browsers outside of Firefox.

Things I've tried so far: Troubleshoot mode/safe mode, clearing cookies and cache, uninstalling and re-installing Firefox

Nothing has helped... wondering if this was caused by an update?

continue in /questions/1424778 in Thunderbird section.

Having used Thunderbird for some time, I installed it on a new PC, and found that virtually all my emails on a particular account seem to have been deleted, despite the app being set up to retain them. I checked on the webmail (BT) and they have gone. The account is set up as IMAP - as is another account on the same server, which seems OK. BT won't engage with me on this as they "don't support third party apps" I assume that 3 years worth of important client history is gone for ever? Can anyone suggest what I did wrong, or is this a software failure?

Locking this thread.

My computer use to start up in Yahoo, now it starts in Google, and I have to open Yahoo from Google. How do I get it back to starting up in Yahoo?

I'm getting daily warning notifications from Mcafee about some virus. Don't even have Mcafee. When I go to Settings -> Privacy & Security -> Notifications, there is no Settings button to modify push notifications.

I have Firefox installed on two PCs. I see the option to add "Recommended by Pocket" under Settings/Home, but on the other one I don't. Screen shots of both are attached. I have completely uninstalled, cleaned up all Firefox files and re-installed Firefox multiple times on the PC where I don't see the Pocket option but nothing changes. Also gone into about:config and tried making changes from there. I want the Pocket recommendations to show on the Firefox Home page for both PCs.

Thanks

I don't know why the page https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es is marked as insecure in Firefox. I tried in Chrome, Edge, IE... and the page is marked as secure, the certificate is recognized.

I attach screen captures of Firefox and Edge examples.

I've the security.enterprise_roots.enabled setting enabled.

If I check for Firefox error details, I see (auto-translated to english): https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es The issuer of the other end's certificate is not recognized. Strict HTTP transport security: false Setting HTTP public keys: false

So I synced my bookmarks then I notice that all of them are mixed up, so i look for ways to fix them, I then see I can restore my files, I try it then it says it was unable too, and then after that it deleted everything, I tried to restore them again and again using different dates but nothing worked.

p.s. I did post this earlier but it was in the middle of the night, so nobody saw it.

I am unable to login to my Prescription provider's website (which I do every day). Problem started Sunday and still persists.

I am able to login using Chrome, so I know the website is working properly.

Help - I DO NOT want to use Chrome.

Using Firefox version 99.0 (64bit). When I click "Bookmarks / Manage Bookmarks, the listing defaults to the "Other Bookmarks" folder. I would like it to default to the "Bookmarks Menu" folder. How do I make it do that?

Hi! I was wondering why nearly every single page these days opens to the message :

"400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Apache Server at canvas.instructure.com Port 80"

Nearly every link I click on a website refuses to open! It has become impossible to do school work on this browser because I can't open any link on my school website, and nearly every website struggles to open except from google. I know the links work because I copy/paste them into Google Chrome and they open immediately. Truth be told I prefer Firefox and would much rather keep using this browser! I also can't find an update for Firefox so I believe my Browser is up to date (and I know my laptop is up to date and virus free). Is there a fix coming soon? Or a setting I can change to be able to open links? Classes start this week and I'm stuck!

Thanks for your help!
