When using Firefox on OSX (Ventura 13.4) after about 1 day Firefox slows down so much I have to quit the application and restart it. Then it is back to normal speed. I'm not sure if this is an OS-X issue or Firefox issue, but restarting the app fixes it for a few hours, then its incredible slow again.

I use mozilla on two machines. They both have gotten to where they lock up when trying to access a second page. The normal place they lockup is "waiting nexusensighten.com". I talked with etrade and they had me try MS edge. It works without a problem. I've started having the same problem with yahoo mail.

I deleted cache and cookies numerous time. Etrade guy had me just type etrade.com to get started. It didn't help.

I update automatically. Thanks for your help.

Good afternoon,

I've got a problem with add-ons while using Squid MITM Proxy with a custom certificate for Firefox/LibreWolf.

While I'm trying to update / install an extension / theme, it fails with:

``` 1686147276233 addons.xpi WARN Download of https://addons.mozilla.org/firefox/downloads/file/4104397/witchdoctor-2.0.xpi failed: [Exception... "Certificate issuer is not built-in." nsresult: "0x80004004 (NS_ERROR_ABORT)" location: "JS frame :: resource://gre/modules/CertUtils.sys.mjs :: checkCert :: line 177" data: no] Stack trace: checkCert()@resource://gre/modules/CertUtils.sys.mjs:177 onStopRequest()@resource://gre/modules/addons/XPIInstall.jsm:2514 ```

How can I install an add-on while using the MITM proxy?

Usually when I start my browser for the first time, I have the Firefox homepage only. For two weeks ago, suddenly an extra tab show up when starting: A page with a commercial for installing "Avast Online Security & Privacy (Add to Firefox-button)".

I use Avast, but I don't want this add-on. And I certainly don't want that extra tab every time I start my pc.

I have three times searched for a solution all over in the Mozilla & Avast settings and on the net: I should go to "Add-ons and themes" - "Extensions" - and on the list "Manage Your Extensions" I should remove this add-on - but it's not there of course, because I didn't install it.

So how do I remove this tab from showing at start-up? (Google Search can't help) Appauling that someone put this tab on my pc in the first place. Both Avast and Mozilla have other ways to communicate with me about that add-on, if needed. Now I had to shut it down every day for two weeks, because I was way too busy to write you until now.

Hope you can help me.

Best regards Finn Larsen finn@fatekst.dk

Firefox version 113.0.2 on Windows 10 Displayed: Error code: SEC_ERROR_OCSP_MALFORMED_RESPONSE

Website loads fine in Chrome and Edge. Certificate verified as valid. Website hosted on SquareSpace. This is a known issue with Firefox as there are many reports with Firefox falsely reporting this error with websites hosted on SquareSpace. Occasionally happens with major sites such as google.com.

      • Verified Firefox issue as there are many reports of this issue.

Cache and all site data cleared. No Proxy set. Endpoint protection security software disabled.

As this is a known Mozilla Firefox issue this needs to get fixed now!

We have released a browser add-on that works with apps using NativeMessaging, but it stopped working after updating Firefox to v114 on Windows 10 (64bit). We have confirmed that it works up to v113.0.1. The browser add-on manifest is v2. In the Mac version using the same browser add-on, the application can be linked even after updating to v114. The behavior of the bug on Windows is similar to the behavior when NativeMessagingHosts is not written in the registry. Is there any information about solutions to problems or causes?

Expected results: Launch app via NativeMessaging from browser addon

like the title says, i installed the latest Firefox update and my graphics driver started crashing every few minutes. tried updating my graphics card driver (Nvidia RTX3070) and tried to set the browser to software rendering, but nothing helps, it keeps going black and restart every few minutes.

There really should be a option to revert from a update, i had this a lot with Firefox, troubles after updates. And with no way to fix it, so i have to use another browser until it is fixed..kinda troublesome.

Whenever the Firefox browser updates, it asks me to close the browser and will not let me open up any new tabs nor update existing tabs without a 'close your browser' message popping up. This is incredibly inconvenient for me. When I'm doing something important, like filling out a form, and it updates. I often have to close the tab that I'm doing something important on and then having to redo EVERYTHING. I would really like it if Firefox would ask or remind me to update instead of force one on me and disabling what I can do with the browser until I do.

Hi

Automatic video play has been quite a nuisance in spite of using some recommended measures, such as under Firefox Settings => Privacy and Security => Permissions => Autoplay => both options set to Block Video & Audio and saving. The settings change does not appear to work.

Since I mostly use the Portableapps.com version of Firefox, I suspected it might be the issue, after noting once you restart Firefox, that the settings are both back to = Allow Video & Audio! I immediately checked out a separate standalone Firefox installation which I updated to 114.0 (64-bit), but to my dismay, noticed it does also not keep the preferred "Block Video and Audio" settings, also when the browser is restarted.

So is there a bug in the Windows versions I use on my Win 10 64bit and if not, which would be strange, what is going on, why are the settings not kept and how can effectively stop auto-play, which can be a nuisance.

An example of such videos is on Huffpost, such as https://www.huffpost.com/entry/jake-tapper-brianna-keilar-cnn-gop-race_n_647ece5ce4b0b4444c80b001 where the DeSantis video immediately loads and starts playing. The Settings save does not appear to work at all.

Thank you for you help.
