Browser bugs

Some issues can't be fixed in the Group Speed Dial, because they originate in the underlying browser engine.

Here you can see some notable issues. You can view them, vote for them, or even fix them (if you are a skilled programmer :)).

Firefox issues

• page thumbnails may miss some semi-transparent elements - breaks screenshots
• page thumbnails may not show some CSS effects, like "blur" - breaks screenshots
• Android homepage Shortcuts favicon is not fetched from extensions page - bad homepage icon
• Page content can move 1px after scrolling - Live dial content shifts 1px after scrolling
• "Undo Close Tab" and short-key "Ctrl + Shift + T" will now reopen hidden closed tabs! And make them visible. - quite annoying!
• cannot load file in the popup - popup window cannot load any files
• requesting permissions from popup window is not visible - exporting backup first time won't work (bad UX)
• Prevent closing Firefox when updating addon (which closes that addon tabs) - can break addon
• PBKDF2 with SHA-512 has poor performance compared to Chromium - I can't use strong SHA-512 in Firefox
• Scripting API can't inject into newly created tab (race condition) - can randomly break certain features

Chromium issues (Chrome / Edge / Brave / Vivaldi)

• Feature request - extend "chrome.tabs.captureVisibleTab" API with rect parameter - would allow less visible thumbnail generator
• New tab page extension reported as not accessing the current page (new tab page) - with the above bug would make thumbnails generator less annoying (almost invisible)
• Implement "chrome.tabs.captureVisibleTab" for the Offscreen Document API - would make thumbnails generator completely invisible
• Calling "captureVisibleTab" fails on the "new tab" page if the extension overrides it - same as above
• scripting.executeScript can't inject into own extension pages - would simplify my code
• Create chrome.offscreen.executeScript API for easy DOM API access in the background script - would simplify everyone's code :)

Workarounds for some problems

Firefox issue - disabling history breaks extension

If you change your Firefox settings to "Never remember history", it will make the internal IndexedDB database "read-only".
Then when you perform almost any action, you will see an error message, saying something like:

InvalidStateError: A mutation operation was attempted on a database that did not allow mutations.

How to fix it:

1. open Firefox settings / Privacy and security tab:

   about:preferences#privacy
   

2. scroll down to the History section and enable "Remember history" option:
