All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

Hello,

I wanted to customize my Firefox new tab with a local HTML file, such as "/path/to/my/index.html". It was possible to use this workaround: https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main

Which implied a configuration file (sometimes named "autoconfig.cfg", "firefox.cfg", "local-settings.cfg" depending on the guide since the name is arbitrary) with javascript code. In the new Firefox 136, this code fails to execute due to a new API being used.

If you want to customize your new tab, follow the previous guide, but on the configuration file write this code instead:

// My new tab
try {
  const ff = {};
  ChromeUtils.defineESModuleGetters(ff, {AboutNewTab: "resource:///modules/AboutNewTab.sys.mjs"});
  ff.AboutNewTab.newTabURL = 'file:///path/to/my/index.html';
} catch (e) {ChromeUtils.reportError(e);}

Note that the file must start with a comment

Adapting the "/path/to/my/index.html" to your needs.

Thanks to @mkaply (github) on this thread https://github.com/mozilla/policy-templates/discussions/1190 for the new API method.

I post this here in case someone has the same issue, because is quite recent and hard to find on the internet.

I was tracing some network activity for an unrelated issue and noticed that when FF starts up it immediately makes multiple TCP connections to livejasmin.com. I have this site blocked by the Windows Firewall and have the host file direct it to 127.0.0.1 so nothing is actually going in or out, but why is FF doing this and how can I fix whatever was done to enable this happening?

I have cleared all cookies and cache, and disabled all addons, and even started in safe mode, but regardless of what I do the very 1st connections that FF makes are always to livejasmin.com, which is obviously not a legit place for FF to be doing any of its routine updates or optimization tasks. My home page is https://google.com and the livejasmin.com connections appear before the 1st attempt to connect to google so this is clearly something malicious that found a way to get into FF early in the startup process.

I have also run 2 different scans tools on the entire computer and both found nothing. I have reviewed all the running processes and do not see anything suspicious either. I do not see this issue with Chrome or Edge, just FF which is my primary browser. All browsers are updated to the latest version as well as the WIN10 OS.

I have also removed my profile and started FF up without the profile, and I noticed the livejasmin.com connections again while the FF "your profile cannot be found" error message popped up. When I had FF make a new profile and set it as the default the same connections to livejasmin.com were made when I restarted FF with the new profile. So it is not tied to my profile.

When I load the video the page loads like normal, all comments and everything is there except the video square is not there. cant see the video, anyhow. even if i move my mouse cursor on it on the start page, the little video wont play the preview. no video player at all. anywhere.

My search engine has stopped working. I just get blank pages when I enter any subject in the search bar. I am forced to open a private window which always works without issues. Closely related to this problem I believe, is the fact that any online forms I try to complete and submit will not submit. Again if I copy and paste the address into a private window, I can complete and submit without any issues.

It is getting very frustrating to keep having to go private windows.

When I open a new tab, it opens fine, I get all the articles as per normal. But when I enter my search criteria I get nothing (see attached screenshots)

Since the last update, Firefox is not working properly. The search engine is completely dead, not working at all, and anything related to Google, like Gmail, never opens. I've tried several things, but nothing works.

Two financial websites I normally look at with firefox suddenly have no images anymore. I think it's the last Firefox update that caused it. Both websites look okay with Chrome.

i use the duckduckgo as a searchengine , so i got some issue while searching . the issue is whenever i search any thiing on the websearch the response i got is totally blank you need to look at this so i added the screenshot

Hi, unwanted site opens every first start of mozilla after PC has been reloaded.

the site is: „www.url-advertisement.org”

I've scaned with malwarebytes, did a refresh of mozilla browser

The website WSJ has large areas on front page, including the opinion listing, are simply white and not 'there' on the page to click on. I've deleted their cookies without effect, tried turning off all adblockers, shut mac down to reboot, nothing seems to have an effect. This is a recent glitch of only several days, prior performance was great. Thanks!

This does not work anymore and I get an edit drop down with copy, paste etc It works on Chrome and Safari. I checked the config for "browser.fixup.alternate.suffix" and it is set to .com.

Hello,

I want to open this URL: https://compatibility.plantronics.com/deskphone Firefox 136.0.1 tells me: SEC_ERROR_REVOKED_CERTIFICATE

The same URL opens in Chrome and shows no sign of a security problem, as far as I can see (Chrome info attached).

What could be the cause? Firefox being to strict or Chrome just too relaxed?

Thanks in advance.

Firefox says versions earlier than 115.13 will be impacted by the certificate expiration. I've updated to 115.21 My add-ons are still disabled. https://support.mozilla.org/en-US/kb/root-certificate-expiration

It seems many don't know or haven't noticed but merely running an esr branch (rather than a developer edition) will also give you the option to enable add-ons with expired certifications via about:config.

Anyway, the "legit" way isn't working.

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.
