linked issue "zeroknight" recommended not signing in to sync? I have not tried this as one of the reasons I use firefox is for the sync capabilities.

You can remove Clipboard from the address bar choices as this new choice has been reported to cause this issue in case there is large content on the clipboard.

The location bar drop-down list can show history items, bookmarked pages, pages opened in tabs, top sites, and search suggestions. You can set what suggestions show when you enter an URL in the location/address bar bar.

• Settings -> Privacy & Security -> Address Bar — Firefox Suggest:
  Browsing history
  Bookmarks
  Clipboard
  Open tabs
  Shortcuts
  Search engines

my firefox does not show the "Clipboard" option. Is there a different way to toggle that off?

What Firefox version do you use as clipboard got added in 125?

For older version this might be a problem with an extension or with the places.sqlite database that sores bookmarks and history.

You can check for problems with the places.sqlite and favicons.sqlite files in the Firefox profile folder.

• use the "Places Database" -> "Verify Integrity" button on the "Help -> More Troubleshooting Information" (about:support)

If errors are reported with "Verify Integrity", close and restart Firefox or reboot and retry.

I was on current release 125.0.3 - followed directions in another guide to install beta channel 126. Now I am stuck on 126 as my profile is not compatible with 125 anymore. Nightmare. 126 does not have clipboard but I unchecked a couple of the suggestion options and it seems stable so far. I will have to wait for 126 to be release channel so I can retain my open tabs etc. in my profile. I will update this ticket when I get release 126.

Thanks!

Firefox 126 is in release candidate stage and should be released next Tuesday (May 14).

They may have disabled clipboard remotely to address this issue, you can check this pref in about:config to verify.

• about:config => browser.urlbar.suggest.clipboard => false

It was still on in the 126 beta. I turned it to false in about:config and firefox froze immediately. :( It seemed stable but when I pasted a short string into url bar it froze again.

If you disabled suggestions from the clipboard, that should fix the problem of Firefox freezing immediately when you click in the bar -- before pasting. It can't help with what happens after pasting.

It's possible that pasting in the address bar runs code to try to extract a clean URL, unlike pasting in other boxes. If so, that sounds like the same underlying problem as the suggestion scenario.

Still seeing freezes after pasting even with clipboard suggest off. URL bar is highlighted blue, but my copied text is not visible after ctrl + v.

I found windows key + v shows my clipboard history and lets me clear it, currently only short text entries are in the clipboard so probably not related to copying files or images.

Not sure what to explore next.

If you paste into a regular form (like the box I'm typing in now), do you ever encounter this kind of freeze?

no I have not seen this issue with forms, only on the URL / address bar.
