It works like magic for speeding up loading new page with online videos. THANK YOU!

Microsoft ignores Linux related user-agents and open web-version of MS Teams in FF browser page instead of launch application. With this best extension the MS Teams join-meeting-URL in Linux FF forwarded to MS Teams Application if any windows related user-agent was selected. It will work automatically if "Override for domain" option was selected. Thank you for making our lives more comfortable!

Thank you, this gets me past Google's disgusting practice of forcing a 6-second loading screen on Youtube for Firefox users. Excellent addon!

A very useful add-on. Thank you very much.

Works great but it seems to cause problems with Cloudflare's website protection now. For example, going to https://www.podchaser.com/, the Cloudflare check just keeps resetting after clicking the "confirm you're human" check. Disabling the addon makes the Cloudflare check not appear at all

perfect

The "switcher and manager" that comes up at the top of the search sometimes doesn't work well, but this one is simple but always works.
i prefer this one.
can also enter or correct UA preset manually.

Easy and decent User-Agent switcher. But missing an overview function for the exceptions / overrides i make for the many domains i visit. Now it is only possible to view/add/change an override if you are on the specific website.
An other thing which can be improved is the user agent set. After installing this addon i did not notice any updates (like version number increments) on the set of user agent strings, you have to do this yourself. [i was wrong, there are some weekly/monthly updates]
But the Firefox user agent is not correct: "Mozilla/5.0 (X11; Linux x86_64; rv:115.0) Gecko/20100101 Firefox/115.0" should be "Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/115.0" see the rv:109.0 reference.
Beside that, working great!

thanks a lot.

Just wanted to test if I can use Microsoft Bing (Chat GPT) also under Firefox, in which I simply pretend as if I would call bing with an Edge browser.

After reading my user agent in Microsoft Edge and manually adding it to the table of the Add-On, no problems at all.

Now I can use Bing-AI with Firefox, easy

For this 5 stars :)

bro i am trying to test it on this website
https://webbrowsertools.com/useragent/
its saying
UA string detected by [normal] navigator.userAgent is different from UA string detected by [aggressive] iframe navigator.userAgent
What to do to hide it from being detected by iframe one . Thanks G

Works wonders for the crappy websites that want you to download their crappy app to just view some quick content. Back in 1992 they invented the web browser so that we wouldn't have to install every website in the world!

Nice workaround for the block on Bing chat AI

It can't fool the Chrome Store to let me install extensions. But the Chrome Store has extensions that allow Firefox extensions to be installed!

Pains me that Mozilla has removed INCREDIBLE extensions or simply blocked them from being enabled. For example: I have a right to view Google's cached results, which even Google agrees to by virtue of having similar extensions on its own Chrome store. But Firefox blocks Come Back Cached Link and doesn't seem to have any other similar extension to replace it.

Jealous much, Mozilla??

There are a lot of other really nice addons that pose ZERO security issues that Mozilla blocks. The devs should be ashamed.

I confirm this addon works in Firefox for Android 68.11, Android 12. But this add-on is not in the very limited add-on list of Firefox for Android, So it must first be downloaded using computer ("request desktop site" may work also), open the downloaded xpi file with Firefox for Android 68.11, then select "allow" in popup dialogue. No convoluted process of nightly version needed. Version 68.11 seems the last that could install add-ons and set about:config, so do not update!

Just needed to download Windows ISO, rather than Media Creation Tool. Worked like a charm.
