  2. Seems like a potential issue. We've got a number of people sharing about issue with Twitter after 126 update: * https://twitter.com/Mouse140/status/1790634060538433988 * https://twitter.com/AI_Spam_404/status/1790731137813483840 * https://twitter.com/paul_wilson_nz/status/1790646345356984411 * https://twitter.com/Nicko_Realist/status/1790635862285533274 * https://www.reddit.com/r/firefox/comments/1ct87u2/twitter_stopped_working_on_os_x_firefox_esr/ * https://old.reddit.com/r/firefox/comments/1csg9gd/twitter_not_working_on_firefox/ I can't reproduce the issue from my end, so looking if anybody can confirm this.

  3. CSS zoom

    This may not affect a lot of sites -- I think it may have been mentioned for Microsoft Office and Google Docs/Sheets -- but Firefox 126 finally supports the CSS zoom property by default.

    This should enable website scripts to zoom content in Firefox more easily and more comparably with other browsers, but if the site has been using workarounds in Firefox (or hiding this feature based on user agent), users could see some odd behaviors when using sites' zoom features.

  4. There was an issue with Firefox Sync which is being resolved - users having trouble should trying again in a couple of hours time.

  5. ...I posted that this update cause my ad block to stop working...and its gone...why? This update was causing so many issues I installed 125...but Firefox would not let import every customization I made to it. Why?

    Seems like a potential issue. We've got a number of people sharing about issue with Twitter after 126 update:

    Many said that changing ETP setting from Strict or disabling it altogether fix this issue. We've also notified the Firefox team to look into it.

  7. Hey folks, the team recognize the Twitter issue as an incident and they're currently working on a fix. If you see any questions around this, feel free to direct people to this thread, which we'll update once we have a more permanent resolution.

    Thanks y'all!
