Hi, how would you do that in MS Edge or in MS IE which is still in Win10. ??

I don't know because I don't use Edge.

That sounds more like a Windows 10 issue and should be asked in a Windows help forum.

It's a Windows 10 issue only if Firefox supports (the unknown) gesture to switch tabs in full screen mode while using the tablet interface. I'm making the (grand) assumption that Firefox engineers are well versed in Windows programming conventions and know if this is possible or not. The issue is not with Edge or Windows 10 per se; it's with navigating Firefox (60 and counting) on a Windows computer - arguably the most popular use case for Firefox currently.

I believe it has to do with Accessibility Services : https://support.mozilla.org/en-US/kb/accessibility-and-ppt Note it can cause excessive ram usage, over heating and is not secure.

Sorry, old URL So reverse below and test it : Please : go to the Firefox 3 Bar Menu --> Options --> Privacy & Security panel and under Permissions the last one check (put a tick in the box) the setting to Prevent Accessibility Services from accessing your browser.

Pk - very helpful. Just trying to figure out what the gesture to switch tabs is (essentially the equivalent to “control-tab” using the physical keyboard). If I enable the multiprocessing, I still need to know what Firefox considers as the accessibility gesture using Win 10 touch.

Am looking, stuff has been discontinued that worked with the old URL, new stuff is not allowed yet.

Enabling Microsoft 10 onboard screen keyboard would solve this issue rather quickly so can move around with the keyboard.

Some stuff here but is keyboard for some and others .... https://www.accessfirefox.org/

PK - stellar work. Thank you. As you're probably aware, the tablet keyboard in Windows 10 doesn't appear unless the cursor is placed in a text field. What I'm trying to find is a gesture I can use in Firefox that is the equivalent of Cntrl-Tab. A two-fingered swipe down from the top of the screen will cancel full screen but not bring up the tab switching icons of Cntrl-Tab. Changing any accessibility settings, unless I'm missing something, will still not allow tab switching using a simple gesture (eg., go to next tab to the right).
