User-Agent: Opera/9.80 (Windows NT 5.1; U; ru) Presto/2.2.15 Version/10.10 Build Identifier: 3.5.5 That's not a duplicate of Bug 221036. Because 1) I tried to set browser.cache.check_doc_frequency=1, but no luck. I discovered that Bugzilla does not send Expires header, and tried to add it (already expired, i.e. date in the past) - still no luck. Same with Cache-Control header. and 2) After updating the second tab, the form itself IS updated, but the flag field IS NOT. and 3) LiveHTTPHeaders says Firefox DOES re-request the page. Reproducible: Always Steps to Reproduce: 1. Open some bug from Bugzilla. 2. Set some flag on it. 3. Open bug in two tabs. 4. Clear flag in one tab. 5. Switch to another tab and click Update (or hit F5, or Ctrl-R). Actual Results: Look at the flag field - it is not updated, but the form itself IS! (for the proof - look at the value of delta_ts hidden input). So if you enter some changes into this form and click Commit, the cleared flag is RESET again WITHOUT conflicts! Expected Results: ALL form fields MUST be updated when updating the page.
Trying to test it in this specific Bugzilla instance.
Hmm... Didn't reproduce here. :(
That's the expected behavior, see bug 46845 and its tens of dupes.
