Turning JavaScript on and off in TFF FPR 7 ... and other questions

Dear Friends:

I’m a long-time user of TenFourFox v10, with OS 10.4.11, and dialup. No TFF add-ons.

I’ve installed TFF FPR 7.

A few questions, if I may, that I haven’t been able to resolve on my own:

• A key website I need (http://abebooks.com) will require TLS 1.1 or higher.

MY QUESTION: Will TFF FPR 7 fulfill this?


• Just a few websites I need absolutely require JavaScript (example: http://mscdirect.com, to filter results by “Made in U.S.A.” and size).

I only need JavaScript for about 15 minutes a week. The other times, I prefer not to enable it; it runs very slowly with a dialup connection, and is sometimes bloated.

I went into FireFox 3.6.28 Preferences, and checked JavaScript. I thought TFF would read this setting.
It did ... but it also wiped out my Bookmarks, in both TFF 10 and TFF FPR 7, built over many years.
Fortunately, I was able to restore them.

MY QUESTION: Is there a way to enable JavaScript in TFF FPR 7 just for those occasional websites where I must have it for fifteen minutes a week ... and then to disable it the rest of the time?


• MY QUESTION: If I lose Bookmarks and TFF history again, can I just replace the entire “ail9fxvp.default” folder in Users - admin - Library - Application Support - Firefox - Profiles?

I’d source this entire folder from an external hard drive, backed up with Carbon Copy Cloner regularly.

– Would this be as good as resetting TFF’s profile, without the risk of losing history, web form fill-out info, etc.?


• After losing the Bookmarks, I see 5 folders in TFF 10’s “ail.9fxvp.default” folder, all ending in .corrupt (example: “content-prefs.sqlite-1.corrupt”).

MY QUESTION: Can I leave these, or will they make trouble down the road?

And, from a pre-corruption external hard drive, can I just replace the entire “ail9fxvp.default” folder in Users - admin - Library - Application Support - Firefox - Profiles?

TFF is absolutely priceless. I’m determined to stay with 10.4.11. Thank you for making this possible!

    1. TenFourFox supports up to TLSv1.2, so 1.1 is no problem.

    2. Mozilla removed the checkbox for JavaScript from the preferences, so it is no longer user-exposed. I don't have any plans to add that back. However, you do have two options: NoScript (using an earlier version compatible with Firefox 45, on which TenFourFox FPR is based), or going into `about:config` and manually changing `javascript.enabled` to `true` or `false` as appropriate. I'd go with the first option first and see how far you get. The old versions are here, you want version https://addons.mozilla.org/en-US/firefox/addon/noscript/versions/

    Also, a note on the bookmarks: yes, this is documented; the bookmarks format changed. It's all over the release notes, which is why we recommend folks read them. The release notes are linked from the main TenFourFox website.

    3. Yes, you can simply replace the entire folder, but *never* do this while TenFourFox is running.

    4. You can remove these "`corrupt`" files, but I'd wonder why they are occurring. Are you switching back and forth between TenFourFox FPR7 and an earlier version of Firefox or TenFourFox? If you do that, you run the risk of data corruption, and that may be what is occurring.

    To everything Cameron said I'd like to add that there is a simple add-on that provides a toolbar button to quickly switch JavaScript on and off. Also there is a similar add-on for images (good for dial-up).

    Dear Cameron:

    Thank you so much for your thorough and most helpful reply!

    I'm following your instructions, and so far, I'm back in business.

    The Bookmarks were imported fully, including their individual icons
    (which were all lost).

    Yes, I'd been occasionally closing TFF FPR7 and using TFF v10 - once
    every few days, when I absolutely needed JavaScript.

    Perhaps that contributed to the problem.

    I'll refrain from doing that!

    Dear Chris:

    Many thanks for your much appreciated reply!

    I downloaded QuickJS 1.3.1, and allowed it to be installed.


    TFF - Tools - Add-ons: QuickJS listed (see screenshot below), but its
    icon is nowhere to be seen.

    (Clicking "More" shows its location is supposed to be at left of menu

    Then, I went to about:config, and toggled javascript.enabled to
    True ... Still no QuickJS icon.

    Then togged to False ... Still no QuickJS icon.

    Finder, all files with name "QuickJS": 0 results.

    Yet, QuickJS is listed in TFF - Tools - Add-ons, with choice to
    Disable or Remove.

    What did I do wrong?

    Toggling javascript.enabled in about:config absolutely works. I was
    able to complete a purchase on a bloated website known to require TLS
    1.1 and JavaScript, with no problem.

    If I should have posted the above on your website, my apologies.

    Click View>Toolbars>Customize…. You'll find the QuickJS icon at "additional Tools", just drag it to the toolbar.

    Dear Chris:

    Thanks again for your kind assistance.

    I followed your instructions, moved the icon to the toolbar, and it's
    working fine.
