Firefox extensions are exhausting my CPU like a malware (it seems like it...) and i can't figure out which one is the problem

Hi Team, As I have created an Extension which is supposed to be compatible with you browser extension market place, when I tried to upload file via you "Add On Developer Hub" it shows an error neither it accept any zip file. Can any please suggest me the best possible way to share my project files with you tech team to review?

The google page keeps showing up every 20seconds, I try to close the page down but it keeps popping up and I do not know how to stop it.

Please can you assist.

Thanks

Sabrina

This question is about a specific Firefox add on. I have not used extensions or add ons previously and am concerned about the safety of the one I want to upload: Claude Conversation Capture.

The page says it will require permission to Download files and read and modify the browser’s download history (which is fine) and Access your data for all websites (which scares the heck out of me.)

How can I safeguard my privacy and data to prevent a breach and maintain proper security if I download this add on?

Can anyone help with this please? The add on would be extremely useful but not at the expense of my security and privacy.

FWIW I am #notageek and very tech challenged, so please explain anything I need to know in ordinary language I can understand (will be greatly appreciated.)

Thank you!

I’m using Firefox version 134.0.2 in MacOS 15.2 with 1Password version 8.10.56 for Mac. The 1Password extension is enabled and the app is open and unlocked but each time I open a site requiring login and password I get a pop-up telling me to, “Press the 1Password icon in your browser’s toolbar to unlock.” This requires me to unlock 1Password again to enter the site’s login/password combination. Not sure if this is a Firefox or 1Password issue but it’s annoying. Any thoughts on a resolution? Thanks

Hi all,

I'm an English speaker in Germany, and I'm trying to add amazon.de as a search shortcut, using the official steps (right click on address bar, choose 'add Amazon').

However, I'm getting the following error: Firefox could not download the search plugin from: https://d2lo25i6d3q8zm.cloudfront.net/browser-plugins/AmazonSearchSuggestionsOSD.Firefox.xml

I've seen similar calls for help that seem to stretch back years, but alas they appear to have had slightly different symptoms/solutions that don't seem to apply to my situation.

Cheers.

Why there is no way for me to review or rate add-ons for the Firefox? Many years I am using Firefox and sometimes I just cant understand what a strange bugs I am facing.

I was in the middle of a bunch of work and this Avira pop up showed up blocking 1/3 of the screen. Probably a scam, but no way to get rid of it. Finally I had to reboot. I googled options and none of them worked. I have been getting Avira "scare tactics" but they were easy to close. But this was extremely annoying. If this continues, how to I get rid of it??

Is there anyway to force actual mozilla pages to be displayed in a dark mode instead of the blinding white background that hurts my eyes to view ? Thanks, David

Some sites I use will not let me use them unless I stop using add blocking. I have not installed an add blocker so I am thinking it must be one in Firefox. Assuming this is true, how can I discontinue the add blocker at a specific site so I can access/read/use its contents. Thank you in advance for any help you may be able to provide. Ken

Good morning,

Youtube has blocked my access because Firefox blocks the ads. This happens only on Firefox not on other browsers. I have the ads blocker disabled in the settings (see picture attached). Could you please tell me how to get this resolved. Regards.
