I use Firefox on my Mac. I visited a site yesterday that provided some who.is information. When I returned to the site today, the who.is information has been changed. I need to find the cached page from yesterday (if it still exists) to get the data BEFORE it was changed.

How can I do this?

I am on a newer desktop iMac. I only use Firefox. Google is my default. And yet.. Nowhere on my right click contextual menu is there a "Google Lens" option! According to the article on the Firefox home page, just having Google as your default search engine will give you that option on the right click menu. It does not exist, as you can see in the attached screenshot. If I am missing a step, I'd love to know what it is.

Is there a way for me to opt out of any new "AI" functionality/features that would otherwise be enabled by default? Like the tab suggestions and perplexity in search. Having AI shoved down my throat from every corner of the internet is kind of frustrating.

I have an extension called Last Pass installed. Is it possible from Mozillas side to see when it was installed please? I think this would have been installed on 12th July 2022

Also does it sync passwords on phone with desktop, as it seems to have synced a password for a site that I do not recall using on my laptop

From Windows 11 start Firefox v 142.0.1 opens with an entirely blank page - toolbars, graphics, webpage - everything taking over a minute to load up with toolbars and then a further 2 minutes to load www.theguardian.com/uk. Firefox then frequently crashes and on re-start the bookmarks toolbar is empty - yes it is visible. I have been renaming places.sqlite to places.sqlite.old every few days since 27 Aug. The Manage Bookmarks - Library shows all bookmarks when Firefox is behaving but is completely empty when the bookmark toolbar is also empty. Restarting Firefox does not reinstall the bookmarks. The only solution is to restart Windows 11. Any ideas on speeding up and preventing this bookmark problem. Thanks

When my internet goes out and I check if it's back up by opening Firefox, if it's not back up then all the tabs from the previous session get lost if I close the browser. None of my other browsers do this; they all open with the previous session. This is a major issue, because I lose hours of work each time.

Hello, when I first switched from google chrome to Firefox I could not figure out how to create one browser with two profiles like I had with chrome. So I went to about:profiles and created two separate browsers not realizing you all had an option to create two profiles under one browser. I finally figured out how to have to profiles under one browser by going here https://www.tech2geek.net/how-to-use-the-new-updated-profile-manager-in-firefox-2025/#google_vignette but I can not figure out how to sync the google chrome profile that I had previously to this new profile under the same browser. How do I sync this? I hit sync and nothing changed. I am signed in and I can not figure out how to get the browser profile to sync with this new profile under one browser. I really hate how Firefox named both of these Profiles because it is extremely hard to explain this situation.

I'm tired fixing errors which become more complex and solutions are written for people who have the time an knowledge to waste fixing these constant issues in FIREFOX, Time to change browser.

On Firefox, I can't use a chatbot because it says Speech recognition is not supported in this browser. This is my own new website that has a chatbot in it to help people out. I'm trying to test it. It works fine on Chrome and Safari but not on Firefox? Why? I have an IMac computer and my software and operating systems are up to date. Firefox is currently my default browser, but that may have to change, if this can't be corrected. Thanks!

I am writing an email with two photo attachments. Preview will not work (open) for me to double check the correct file is being sent. It will, however, open a file with only text.
