I am trying to install the ClassLink Browser Extension for Single Sign-On from the following URL: https://launchpad.classlink.com/browsersso/741309. This site has been saved under "Permissions and Data-> Allowed websites - Add-on installation" as well as the site that opens when you click the install button. Despite both sites being saved as an approved installer, I am still blocked from being able to install the extension as though the sites are not on the approved list. The extension cannot be found on the firefox extension store, so this is the only way to obtain it that I am aware of. Please help me to resolve this issue, and in the future, work to include an "allow this time" or similar option on the 'blocked installation' popup for sites not on the list, instead of only an "OK" option, so that users don't have to go back and forth through this approval process that doesn't seem to always approve it anyway.

I was assured transition to Firefox was seamless, but everything about it so far has been anything but.!The final straw was 3 step process to sign in to BMO online (just password w/chrome) Here its get verification code or go to extensions, ad blocker off, sign in to BMO, sign out, back to extensions , turn on ad blocker, carry on. Really? Settings suggestions seemed a bit like trial and error, and more time essentially wasted, as I now have a few hours invested trying to make this work for me. I am, admittedly no tech wizard, but neither an I stupid. I am minutes away from reversing the whole process and, much as I hate to, going back to the over-reaching arms of chrome/google. As I am not really expecting a response here, I realize this will just boil down to venting. There is much to Firefox that I liked, but the transitional road-blocks are exhausting . I will say it felt great to finally take that step, however temporary it was.

I look at my email mostly on my laptop. I use the Firefox browser. At the top of the browser on the right side, it shows the number of unread emails. For some reason, when I have zero unread listed in yahoo, it still shows that I have a number of unread emails on top of the Firefox browser.

Trying to add an extension my mypoints.com, I have the site allowed for downloads but when I try, I receive a message that it is blocked from being downloaded.

Здравствуйте! Есть вопрос: есть ли возможность управлять расширением вне браузера? Хотелось бы, чтобы горячие клавиши работали вне браузера. Я использую расширение для музыки, в котором есть настройка переключения музыки горячими клавишами, но вне браузера они не работают. Можно ли сделать так, чтобы они работали, когда браузер свернут? То есть расширить область их применения до глобального уровня.

Hello, I am trying to add extensions from addon.mozilla.org, and any one that I click "Add to Firefox" shows this error code:

"Installation aborted because the add-on appears to be corrupt."

A few months ago, I was able to run extensions no problem (For the ad blocker) until my Firefox application updated automatically and it no longer works. My Firefox continues to update automatically since then and I am not able to use any extensions unfortunately.

Any help would be greatly appreciated. I've been having to use Edge in the meantime, but I would prefer to use Firefox.

Thanks, Ethan

For a long time I've been using ublock origin to block parts of emails and RSS feeds to make them more readable. This is not so much to block ads as to block parts that make it hard for me to read things. I am partially sighted. Flashing text etc. is very hard for me.

Now the extension loads but the element hiding part doesn't work on either emails or RSS feeds. I click on it but it no longer selects any part of the emails or feeds.

Why is this and what other options are there?

It still works on Firefox.
