Diễn đàn hỗ trợ Firefox

I normally use Firefox Developer Edition, version 127 because any later version always freezes my whole computer (probably because I'm using a 15-year old PC). Recently all my extensions became disabled. I'm now also unable to install any extension because it says "Installation aborted because the add-on appears to be corrupt". I found some instructions on Mozilla website about deleting compatibility.ini and extensions folder, but it didn't solve the issue. Now I'm stuck and confused as I suspect some of the extension files that should be in my Profile folder may not be there.

The simplest solution in this case would be to use the "Refresh Firefox" option which resets everything to default settings, but every time I do it my computer freezes until rebooted. Uninstalling and reinstalling manually is also not the way to go, because it retains all the settings.

I've tried installing the standard Firefox browser (v. 119) alongside the Developer Edition but the same issue is there as well.

I'm looking for an alternative way to get a clean Firefox install, so I can fix my extensions.

Additional info: - Your system specs? Windows 10 64-bit, 4 GB RAM, Pentium Dual-core, no GPU - Hardware acceleration? Disabled. - Using any mods? Yes, two. Geckium for Firefox, which always works fine. The recent issue started when I played around with Revert8Plus, but it initially worked without issues.

Firefox crashes constantly when I load it mostly when in youtube though. I notice so I am not sure what is causing it to crash it could be ublock origin as I use that to block ads on youtube that is the only thing I can think of or maybe the return dislike button but here is my crash report below ID bp-8f27f4a1-7ed0-492e-823d-e57af0250304

I used Chrome until two days ago. I just got tired with how shitty the browser was, how bloated it made my computer, and how much Google treats everyone like a data product. However, I use hella google systems from Voice to Chrome to Drive to more and it all worked great together. Choosing to change to Firefox wasn't an easy decision but I knew it was a good one

Which makes it super irritating that some of the functionality is already facing problems. I have shortcuts I built to make it easier to study or do random things so I don't get distracted or tired. One shortcut is clicking a key that should launch UWorld in my default browser & use Lastpass to autologin (I couldn't get it to launch the service but that was a separate issue).

I check if autologin was on for the password on LastPass I've allowed all permissions to the LastPass extension I clear my cookies on UWorld & turned off enhanced tracking protection for the UWorld login portal site

What should I do to fix my one button shortcut again?

I really don't want to go randomly turning off every protection that Firefox gives me to figure it out so I'd appreciate someone who understands the browser better helping me out. Also, bonus points if you can help me build a single shortcut button on my Mac that can launch UWorld & navigate me straight to the question bank. (I do think the issue with autologin on LastPass is going to become more of an issue as I start opening up more websites I used to use on Chrome so I'd rather nip it in the bud before I see the problem occur more often)

ATT.NET is blocking my access to ATT/Yahoo email from my ATT.net account using Firefox ''but not using Chrome?'' I have stopped all tracking and cookie blocking

Trying to browse ebay using Firefox. The pages have become really slow when loading.When scrolling down the page is blank then slowly populates as I scroll down the page. I've just tried microsoft edge and there is no problem.

Hi, We are using Horizon VDI terminal server. Firefox is installed on these servers. Some users get Firefox is already running but is not responding error. Ending Firefox via task manager does not work. I log off the user and have them log in again, but it does not work.

When I check, I see that the user's profile file cannot be created on any terminal server.

Is there a solution to this problem?

Windows 11 23H2 FireFox 136.0.1

When clicking check for updates it firstly shows the rotating arrows icon for a long time and then says "Failed to Check for Updates"

I've completely reinstalled Firefox and this continues to happen

I do not have NordVPN or any other VPN installed

The behaviour is the same in troubleshoot mode

anyone know why I am getting this message all of a sudden,Installation aborted because the add-on appears to be corrupt.FoxyProxy, Wappalyzer and cookie manager all were red flagged , just happened!Cant download anyone of these The OS is Kali linux

I checked my add-ons in settings to see what was wrong as I noticed the icons were missing. Upon looking at the proper tab, everything "could not be verified" (including themes) even though everything was working perfectly within 24 hours prior to the issue arising. When trying to reinstall anything from the extension store, all I receive is a "this appears to be corrupt and thus will not install." Clicking the "more information" button on any/all affected add-ons reveals that everything is unsigned. How do I alleviate this?

When printing a PDF with custom page ranges, the footer text in the print preview (see image) does not match the actual page. As shown in the example image, if I want to print pages 2-16, the preview indicating page 4 is actually page 5.

So, if I want to print with a very custom range, such as 2-4, 6-10, 12-14, 16, it will be very confusing and will take longer to adjust.

And I also print custom ranges like this very often for daily tasks. I’m not sure if this is a bug or just a minor adjustment needed in Firefox’s coding. Thank you in advance for your help.

[redacted] problem you [redacted] im having issues with the video and ads as all of my apps are disabeld nothing works and firefox it self causing probs and no one is helping out.

Have new W11 laptop. Installed Firefox and have set it to my default browser but if I use the search box it opens the results in Edge. Where is the setting to enable W11 search box to use Firefox.

I keep getting nuisance popup prompts to sign into an old gmail account I had linked to my firefox program. I have since deleted this email from firefox and closed the gmail account but keep getting these popups asking me to log into this old gmail. How do I fix this??

I'm on Linux.

I've been using this method to setup a custom new tab page for Firefox for almost 4 years, and it has worked great: https://jamesnorth.net/knowledge-base/article/firefox-new-tab-page

---

Navigate to /usr/lib/firefox.

Create autoconfig.cfg:

// var {classes:Cc,interfaces:Ci,utils:Cu} = Components;

/* set new tab page */ try {

 Cu.import("resource:///modules/AboutNewTab.jsm");  
 var newTabURL = "file:///home/james/ff/index.html";  
 AboutNewTab.newTabURL = newTabURL;  

} catch(e){Cu.reportError(e);} // report errors in the Browser Console

Create defaults/pref/autoconfig.js:

// pref("general.config.filename", "autoconfig.cfg"); pref("general.config.obscure_value", 0); pref("general.config.sandbox_enabled", false);

---

However, upon updating to Firefox 136, I only get a blank page. All of my autoconfig files still exist in /usr/lib/firefox.

When I create a new tab with Ctrl+T, it's a blank page. When I create a new window, it loads the local page I want it to load with the file path in the URL (which it never had before; the URL bar was blank in Firefox 135). So it seems to be partially working.

Any tips?

Hi,

I take a look to forums and docs but didn't find answer to it : just found informations about the use of firefox -P

Is there a way to change the defaults profile path.

For example, in the profiles.ini :

Name=default IsRelative=1 Path=Profiles/be7er9lz.default Default=1

this is a relative path referring to %appdata%\Mozilla\Firefox\[PathVariableValue]

Is there a way to change a config file or config to customise the path for all users a windows computer ?

For example :

setting this variable to \\nameofserver\Firefox\

will made all relatives profiles looking for : \\nameofserver\Firefox\[PathVariableValue]

without this option, I should be obliged to edit all users profiles.ini to change path to absolute

Thanks for your help

Hello. I have a problem with Firefox since today. When I am on YouTube I no longer see the thumbnail image of the video. However, when I am in private browsing it works fine. How can I fix this? Regards, Julian.
