Firefox: Shortcut Strg+Tab causes Hang-Up - Which Addon could be guilty?
hi i got several addons and now every time i use strg and the key t (or strg+shift+tab) to switch tabs firefox hangs up :(
How can i find out which extension uses which shortcut to change it?
Is there an addon to show all shortcuts with usage of which addon?

CTRL+T opens a new tab and CTRL+SHIFT+Tab cycles through open tabs.
Did you try Safe Mode?
Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
- do NOT click the "Refresh Firefox" button on the Safe Mode start window

If it works in Safe Mode and in normal mode with all extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) disabled then try to find which extension is causing the problem by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via one of these:
- "3-bar" menu button -> Exit (Power button)
- Windows: File -> Exit
- Mac: Firefox -> Quit Firefox
- Linux: File -> Quit
When multi-process windows in Firefox is enabled then Firefox will use more memory and may be less responsive.
You can try this to see if it has effect:
- set dom.ipc.processCount to 1 if it is currently set to a higher value (4)
- disable multi-process windows in Firefox
You can disable multi-process windows in Firefox by setting these prefs to false on the about:config page.
- browser.tabs.remote.autostart = false
- browser.tabs.remote.autostart.2 = false
You can open the about:config page: via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
