Firefox 支持论坛

I can't import Safari bookmarks into Firefox. I follow instructions and select Safari. When I click "open," it does nothing. I'm stuck. Please help because I would like Firefox to be my default browser.

I would like to make Firefox the default browser on my iMac but for some reason it refuses to load my home page on Facebook. I can get to the general Facebook page and login and see the news feed but when I try to go directly to my wall or home page, it gives me the message "This page isn't available right now. This may be because of a technical error that we're working to get fixed. Try reloading this page." I have tried clearing the cache to no avail. Anyone else have this issue or a possible solution?

I recently upgraded to the latest version of Firefox on my Macbook Air running 10.14.6. When I try to play embedded videos, the video will freeze and there is a message saying that it is slowing down the page. I am in another country with a 50mbs connection and have to use a different browser to watch embedded videos. How can I return to the last version of FF which worked?

When I create a file to print in Firefox ( in this case from Etsy ) the preview looks ok but when the file is printed or saved as a PDF then the text parts of the file are ok ... but the images are much too large.

You can see this on the attached images ... how it should look and how its coming out!?

Any help gratefully received :-)

With another new MacOS update coming soon, I'm curious to know whether Firefox will continue to support older MacOS versions like Mojave and Catalina. I have an almost perfectly functional MacBook Pro first released in 2012 and curious whether Firefox will make it easier or harder to continue using it.

https://wetransfer.com/ doesnt open, the last month. I thought site was down, but isnt. Its the best free FTP site. it will open in safari, which I hate. Please help!
