General problems with downloading AddOns

(Bobo) #1

I have problems with different new AddOns. When I like to install them it says on the respective AddOn page “only in Firefox-Download Firefox” now.
What can I do about it, I have, of course, the actual Firefox installed?

Do you use anything that changes your user agent or “anonymizes” you?

Not that I know. As an example I have the problems with downloading AdBlock Plus which worked before (the problems with the certificates I think in version 66.0.4

I just noticed that I have the problem with any AddOn or Theme.

If you don’t have an extension installed that would override the user agent, please check that you have the default user agent:

Hi BoBo, the following test page will show you the user agent your Firefox sent it in red text:

Example: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0

Some users have had security/privacy software that adds text to the end of the user agent string, which breaks the Add-ons site’s ability to determine that you are running Firefox.

Thanks to everybody, the user agent was not correct. After a reset everything is working now
