it appears this new version 77 Firefox is not working for me in many ways. this issue above and now in Facebook in Firefox when I re post a video from someone and go to my page the video is huge I can not see the entire video it only gives me the 1080 option i can not make it smaller I am using the classic Facebook but it did the same thing when I went to the new Facebook how do i make the video smaller. I see no way to adjust it

Is Firefox your default browser? You can check if FF is the default browser by going to the FF menu > Options > General > Startup. If it isn't the default, click the Make Default button which will take you to the Default Apps section of the Settings app.

That twitter link is just an HTTPS url, so it should be openning using your default browser. If FF is already set as the default, open the Settings app, go to Apps > Default Apps > Choose default applications by protocol. Find HTTP and HTTPS in that list and set them both to open using FF.

Since you've installed the Twitter app, it may have been turned on for links to the twitter website. To turn if off, just click the Apps for websites link and turn it off from there, so that twitter links continue opening with the default browser or the one you set for HTTPS urls.

already done all set properly not so much Firefox it is when someone posts a tweet i get it in my Thunderbird mail and it will not open there or in Firefox it give a re direct says i do not have a an app associated with it. My own page opes but i can not open any tweets posted into my thunderbolt mail or Firefox attachment image i what i get when i try opening someone Twitter post in Thunderbird or firebox yet they open in Chrome. Edge and Comcast mail but not in Thunderbird or Firefox from Thunderbird Thunderbird is my default through Comcast and Firefox is and has been my browser. I have tried with add-ons removed disabled refresh both Thunderbird and Firefox actually reinstalled both and still get the problem

but ks  for your help
I think it is  either a Twitter or  Mozilla problem
it  worked until both the Firefox and  Thunderbird updates recently

i went to hyper links in Thunderbird and put them to true

even with the new thunderbird update i still get the error message and can not open any of the twitter messages in my email

Have you uninstalled the twitter app and reinstalled it?

If you have try this.

• Restart the operating system in safe mode with Networking. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, OSX

If safe mode for the operating system fixes the issue, there's other software in your computer that's causing problems. Possibilities include but not limited to: AV scanning, virus/malware, background downloads such as program updates.

i have twitter through the windows store that is how i loaded it I am on a windows 10 pc it was not loaded through google search does that make a difference

there is no way to uninstall from the programs and features so i have no way to uninstall like i said i got the twitter app from the windows store

I am on windows 10 have the latest Firefox version on  windows pc I get my Thunderbird mail though web mail Comcast the emails from   Thunderbird opens in   Comcast mail Hotmail etc just not with Thunderbird which  also is the latest version not sure how to configure Thunderbird  ok   the initial message pops up in Thunderbird but if  i click on it to open the original message  i get that error message. I do not know of any other  way to downgraded   twitter unless it is  from the Microsoft store. its the free version  not sure if there is a paid version

. In order for me to read the messages from twitter that are in Thunderbird i have to go directly to Twitter sending you a snip it from Thunderbird now as you wil lsee it does open in Thunderbird but when I click where it says read more i get the error message before the 7.0 updates i wa able to get the messgae but not now. it may be because oof the new winndows 2004 update see the capture Like i said i have thunderbird through comcast

not sure if there is a way to configure  thunderbird to open it  there

i installed in the microsoft store. I get that the post come to the email but it wll not open in thunderbird or firefox i hve to go to my accoun to see the and answer the posts

That is correct you have to go to the twitter app.

Update on Twitter Chat.

Twitter Chat has been removed from Thunderbird. https://bugzilla.mozilla.org/show_bug.cgi?id=1445778#c35 Twitter has decided to change the API and is adopting a new one, but seems to be having a delay due to a security issue. https://blog.twitter.com/developer/en_us/topics/tools/2020/introducing_new_twitter_api.html

so let me understand this I can no longer get twitter on Thunderbird correct. It comme up but when i click on it to read it it givesa redirect and says i do not have an ap associated with it

Twitter has caused the problem. They have decided to work on a new API. You can see full info at the link I provided. As a result of Twitter's decisions, connections were failing, so Thunderbird had no choice but to disable. Full conversation at the bug link explaining how they tried to fix, but cannot do anything because of Twitter.

In Thunderbird, if you pretend you want to add a Chat account, Menu app icon > New > Chat account The window that opens does not display a 'Twitter' chat network option.

thank you

I'm not sure what Twitter chat has to do with https links that happen to be pointing to twitter.com not opening.

I am facing the exact same problem as above. I do not want to chat through Thunderbird, I just want Thunderbird to open links.

Like be able to open https://twitter.com/i/redirect?url=https%3A%2F%2Ftwitter.com%2Fi%2Ftopics%2Fnews%2Fe-1037402585%3Fcn%3DZmxleGlibGVfcmVjcw%253D%253D%26refsrc%3Demail&t=1+1602848217861&cn=ZmxleGlibGVfcmVjcw%3D%3D&sig=89efa82ec2eb5af1010701447641dd61f6be35d9&iid=c5614a816e3a4f1aa88d53553d574c0f&uid=420110661&nid=244+272830465 (just as an example) in my default browser or the windows twitter app. Instead I get the same error as described above.

I don't see how changes to Twitter's API are related to simply opening links. Unless the latest Thunderbird update accidentally broke links pointing to twitter.

Yup, I had the same problem, and got around it by doing this. In the Twitter email in Thunderbird, I right- clicked on the link I want to open, and left-clicked on the "copy link location". Went into Firefox, left-clicked in the address field and selected everything in the field, and pressed Ctl-V to paste the link from the email. Press enter, and you're in the Twitter article you want!
