Firefox addons

Anyone else notice your adblock or other add-ons aren't working since the last update? Go to Tools in the menubar and click on Add-ons. Do some or most of them have a tag that says Legacy?
The new update changed the code for security reasons, to keep add-ons from getting wild and turning to malware. We'll just have to wait til the developers update their code.

I saw that too the other day. I rarely use Firefox these days as it is, and just started trying out some other browsers. Brave and Vivaldi were mentioned in another thread here recently, both based on Chrome. You might want to look at moving on if Firefox' add-ons don't get updated in a timely manner.

Off topic, but I came across Firefox Focus, for iOS, so not really pertinent to this thread.

As far as I am aware, Firefox is moving from the old API at a very fast pace and is endorsing WebAssembly. While very popular plugins are being rewritten, others are just bailing out completely. A lot of legacy and dead plugins incoming. Your best bet is to stick with an older version for the time being.
