Firefox Support Forum

Hello guys, this would be a little awkward. Since I've run into this problem a limited number of times and I can't reproduce it. But it does appear frequently and is very annoying. I had to ask here for advice and help.

The device I use is a MacBook, running the official version of Firefox, and as far as I know this problem has been there for at least half a year. I'm used to keyboard operations, usually I use Cmd+T to create a new tab, then the cursor is focused on the address bar, and I type the URL. Since I'm typing an address that I visit often, maybe I just type the first few letters, the URL gets autocompleted, and then I just hit enter and the page opens in my new tab. But sometimes I hit enter twice (eg not English input method). At this time, I noticed that in addition to the URL I wanted to open, there's an additional tab. This tab was blank, or the page I just visit.

From my personal understanding, I may have performed the above operations to create a new tab or clone a tab at the same time. But I don't think my operations will cause these to happen concurrently.

Below are the extensions that I have installed, in my impression I don't get this bug in Windows, but I don't use Windows a lot. In addition, my MacBook keys may be sticky, or it may be a system problem.

The problem is basically in the title. The expected behavior:

1. With FF closed, I click a link in an app or document. 2. FF opens and shows my old tabs in one or more windows. 3. The link I clicked opens in a new tab in the same window as my old tabs.

My browser is set to "Open previous windows and tabs" on restart, and to "Open links in a new tab rather than a new window." I tried some basic about:config fixes as advised here (https://support.mozilla.org/en-US/questions/1331882) with no luck.

Can anyone help me troubleshoot this?

Previously when I would open an attachment in my att/bellsouth email, (powered by Yahoo), it would open in a new tab and also download it and save it to the download folder. Now when I click on attachment it displaces my inbox while still downloading and saving it in the download folder. I did make one change previously; I set it to open downloads in Firefox because if I wanted to open something from the past, it would open in Edge. I don't use Edge, so I set it to "open in Firefox" but now I can't find that setting to see if it is causing my issue. If it's not causing my issue, I will still need to know how to get attachments in my email to open in a new tab.
