Subject autofill feature stopped working in gmail for new subjects only - and I'm not the only one - help!

A few weeks ago subject line autofill for gmail email stopped working. Old subjects from many weeks ago still come up but not new ones. I finally researched in gmail support and see many others with same problem. Gmail says it's a browser issue but settings are correct for remembering history, etc and have not changed. Is there a Firefox fix? Not having this feature is wasting a lot of my (and others) time retyping same subject over and over.

Here's one of the gmail support threads:

Does your auto complete work on other websites, if for instance you delete the auto complete entries from the current site does it remember them again. The auto complete feature works for me on the gmail subject line, so it does not appear to be a problem with that site.

Make sure you are not using private browsing. Is any privacy etc utility deleting this information? See also Firefox doesn't save web form entries

Thanks for your reply but my problem still isn't solved. Yes, autofill works on forms, etc. No, not using private browsing. Gmail says it isn't a gmail setting so cannot change anything there. Did you see the gmail discussion link I pasted into my question -- seems others have same problem but not consistently, maybe even across browsers . Seems it started for some a few months ago though I don't remember it being a problem for that long. It seems to be a real mystery ... an annoying and inconvenient one! Any additional suggestions are much appreciated.

My initial answer could have been better, there does seem to be an ongoing problem.

I did glance at the thread you linked to and a couple of others, but an equally quick look at my little used gmail account revealed a recent subject name showed up ok.

On re-reading the thread and looking at my gmail, I agree my own is not now saving current subjects. Reading the your google thread suggests the problem may have been intermitent and works now for at least one gmail firefox user who previously had a problem.

I have not yet tried this with firefox in Diagnose Firefox issues using Troubleshoot Mode or with a new firefox profile, ( I already have multiple Profiles - Where Firefox stores your bookmarks, passwords and other user data setup ) I may look into this further over the weekend; if no one else posts a solution.

Just checking to see if you had time to investigate further? I'm surprised that nobody else is weighing in on this seemingly widespread problem, especially considering all the discussion in the gmail support forum. Do you agree it is a browser issue?

  • You enter Private Browsing mode if you select: Tools > Options > Privacy > History: Firefox will: "Never Remember History"
  • To see all History and Cookie settings, choose: Tools > Options > Privacy, choose the setting Firefox will: Use custom settings for history
  • Uncheck: [ ] "Automatically start Firefox in a private browsing session"

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.

I will chime in here and confirm that I have the same problem and it is only with Gmail subject lines. Many other websites I frequent such as ebay, amazon, or user forums all remember what I enter in search fields. Problem is, I don't care if they remember or not. I need the subject line in Gmail to remember previous entries and that is the only reason I found this support page in search of a solution.

Did any of the potential solutions offered here work for you? I'm still in search of an explanation that makes sense and more important, a solution that works.

Sorry I forgot about this, and then decided I needed more time to check through the results.

My tentative conclusion is that Gmail probably never has saved the subject line as a Firefox autosave entry (at least not on my XP computers over the last year).

Is anyone able to confirm categorically that G-mail now or previously saved the subject lines, and if so can you confirm it does this with Firefox.

As I said in a previous reply I do not use my gmail account much. So far from what I have managed to check it appears to me that

  • Login - that info is saved by firefox (proves the auto save is working)
  • to line - that info does display options as drop down lists, they appear to be generated from gmails own data
  • subject line - is not being saved by firefox and probably never has been
    even if sometimes some options are displayed in dropdown boxes from the subject line

Trying Firefox 3.6 in a new profile and in safe mode it is still not saving subject line information, but other auto save work including the login details. Where dropdown items appear from the subject line, then in my case they appear purely coincidental, having been saved elsewhere in a field of the same name, but using a different website ie NOT gmail data. The info would be stored by Firefox 3.6 (& 4.0) in the database file formhistory.sqlite I have deleted the file and watched it with a sqlite editor and see no evidence of gmail adding subject line information to the file. I have also looked through existing files comparing by eye the subject lines of some gmail sent items and again am not finding matches.

I also have a webmail account with, I note that also does not save the subject line to Firefox.

As for Firefox 4, I may look again at some other time, I must be doing something odd, or Firefox 4 is behaving differently to Firefox 3.6

Firefox 4 at present seems to be able to regenerate deleted or renamed formhistory.sqlite files; I have not yet managed to run that in safemode with a new profile and no formhistory.sqlite. What is clear is that even in safemode firefox 4 is not saving gmail subject lines.

Of course you should be able to obtain opinion and results from the gmail forum, but I suspect the apparent lack of mass interest may be indicative of the fact most users may not expect subject line information to be saved from webmail to browser, maybe even gmail have deliberately prevented this as a potential privacy problem.
