Older versions of extensions?

My old PC died, luckily, I had a new (secondhand) one ready to go.

I am using a pre-quantum version of Firefox.

Where can I get legacy versions of extensions that I need?

Yes, they've all been updated and maintained, but, there are several whose functions are severaly depreciated - including one where I would now have to actually PAY MONEY to do what I used to be able to do with ease on the legacy version.

Urgently seeking legacy versions that all worked fine before my old PC hit the dust last week.

In the bottom left hand corner of the screen where you can download the add-on from, you will see a link to "All Versions", but I strongly recomend that you do not use old versions of add-ons or Firefox.

You will be using a web broswer that will not have any security and stability improvements and this could put your browsing and computer at risk from malware.

Thanks. I've already tried that. Unfortunately, the versions that I need don't seem to be listed - only the depreciated post-quantum versions.

As regards to security, I use an ad-blocker, script blocker, Malwarebytes-Anti-Malware, I've got my anti-virus set pretty high...and yes, I know I may not be as secure as if I use the most up to date software, but, accessability features that I NEED are eithor depreciated or non-existant from 57 onwards, leaving me with little choice.

All pre-quantum versions were removed from Mozilla's website.

For a time, pre-quantum versions were still listed at a special web address. But that was shut down a long time ago.

They must be available somewhere - very few things totally disappear from the web completely.

I also have Tor browser so can access copyright-infringement sites that are blocked by ISP's if someone has upoaded onto such sites.

Eek, just accidentally flagged one of the posts on this thread by accident and don't know how to undo that....please ignore the flag.

For old "Legacy" Firefox extensions which were built on XUL/XPCOM technology (pre-Fx 57), there is a Classic Add-ons Archive over here:

Never used that source myself, but I am aware of the efforts behind saving the "Classic" extensions in the months prior to Mozilla wiping them from their Addons server.

How do you find the add-ons there?

Install the extension via the releases page.

Found it. Have to look under Contributors > Select a contributor > Repositories. Thank you.
