How to download an add-on?

(Marabu Too) #1

Hi,
I haven’t installed any new add-ons in quite a while - actually since I bought my current PC in mid '18.
Just now (using Win10 with Firefox 66.0, 64 bit) I tried to install a new one (and then, in case the first one was incompatible, several more), and all I could see was “only on Firefox - download Firefox now”.
If I follow that link, I eventually see “You already have Firefox”.
In case this should now be mandatory, I logged in; no change.

Can someone please help me in my ignorance?

Could you post links to where you were trying to download these extensions from?

The Add-ons site is sensitive to certain changes to your user agent string. If you check the red text on the following page, does it have any variance from the usual:

Test page: https://www.jeffersonscher.com/res/jstest.php

Normal for your configuration: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0

Changes could be caused by settings, extensions, or external proxies. For settings, see:

Thanks for the prompt answers!

Mozilla/5.0 (Windows NT 10.0; rv:66.0 ) Gecko/20100101 Firefox/66.0 anonymized by Abelssoft 1845082249

I suppose it may be the anonymiser; installing that add-on is not urgent, so I’ll take a closer look next weekend.

@freaktechnik

no particular links; I simply clicked on
“three lines” -> add-ons -> Discover add-ons
and then took a closer look at a number of them when the one I’d been looking for couldn’ be downloaded.

Yeah, abelssoft’s UA anonymizer is what’s messing up AMO.

Strange - I first disabled the anonimiser function, then unticked “start with Windows” and rebooted, but the message I get when clicking on
https://www.jeffersonscher.com/res/jstest.php
is still the same.
I looked through the list of processes in Task Manager, but if anything connected to the anonymiser is still running, I certainly didn’t recognise it.

Luckily, there isn’t currently any add-on I need/want to install, but the inability to do so DOES bother me (a bit).

That’s because it likely modified your Firefox profile and doesn’t undo the modification when you uninstall it.

Thanks - that was it.

I know very little about about:config, but luckily just searching for “anonym” got me the very string mentioned above - still with “anonymized…”.
All I had to do was delete that bit of the string, and now I can once again install add-ons!

Thanks AGAIN!

My bad: if I had also clicked on your second link when you posted it (and not waited until today), my little problem would have been solved much sooner!
