I want to install 2 extensions, FoxLingo 2.1.4 and abcTajpu 1.3.5.

However I always get the message
"Firefox could not install the file at because: Invalid file hash (possible download corruption)
no matter how many times I try on both of these.

I then tried installing an extension that I did not want, to see if it was a universal problem, Converter, and as sods law would have it it worked!

Are the source files corrupt? If not is there anything I can do my end to fix it?

I am using Firefox

Any suggestions appreciated.

Try getting the extension from their homepage or direct from the mozilla ftp site. I have seen a number of similar reports following the recent update to the Mozilla Add-ons site.

FoxLingo 2.1.4 - ... +mz+zm.xpi

abcTajpu 1.3.5 ... -fx+tb.xpi

I did try and got it first time no problem, so obviously there is something wrong with the Mozilla Add-ons site.

my stop autoplay has the same issue...

you can "download" (right click and save, not left click) the file and the drag it into firefox window.

I have just had the same problem, I could not install anything from the Mozilla Add-ons site however it worked first time when I went to the developers homepage. Definitely a problem with the add-ons site .
