    Please clarify: TenFourFox or Firefox? If the former, which sites?

    If it's every site, that's definitely a pervasive bug that I can't reproduce (I'm typing in it now) and I would strongly suspect an add-on, though I didn't make any changes to JavaScript parsing for FPR4.

    I went to


    I can't reproduce anything like that here. If there is a specific URL that does it consistently, please post it.

    Does this happen with a clean profile? (See "How to reset your profile" at the lower right.)

    I have been away and was unable to continue this process until now, so today:

    - upgraded to the newest FireFox. Worked fine, then :
    - Went to Firefox site, clicked on FAQ link: Got 'Javascript Application. Error: missing format parameter' on a page that said 'Error obtaining wikidata'

    If I exit, that page and visit it again, I don't get the java script again, but do get the wiki data error page.

    So, I went to reset my profile. And her is where I think I am just not computer savvy enough to do this.

    I keep reset profile instructions open on my ipad.

    1) I can't find a Tools section anywhere on my disks. I give up and try looking for other stuff -
    3) I find Application Support in Library. Only Ten Four Fox folder is called Ten FourFox User Guide. It contains two folders - Profiles and profiles.ini
    4) In profiles.ini is tomocgjg.default
    5) In that are: cert8.db

    - Are these the add ons? Either way. that is it. No idea now what to do or how to reset profile.

    Tools isn't a folder, it's a menu in TenFourFox (between Bookmarks and Window).
