Revisionsindhold

Some problems with Firefox are caused by extensions, themes or hardware acceleration. This article will help you determine whether one of these is causing your problem and, if it is, describe how to make Firefox run normally again.

Bemærk: Funktionen Nulstil Firefox kan løse mange problemer ved at gendanne Firefox til sin oprindelige tilstand, samtidig med at dine vigtigste informationer gemmes. Overvej at bruge funktionen, inden du går i gang med en langvarig fejlsøgningsproces.

Start Firefox i fejlsikret tilstand

When you start in Firefox's Safe Mode, all extensions are temporarily disabled, hardware acceleration is turned off and the default theme is used. This will help determine whether one of these is causing your problem.

  1. Klik på menuknappen New Fx Menu . Klik på hjælp Help-29 Klik på menuknappen Fx57menu . Klik på Hjælp, og klik så på Genstart med tilføjelser deaktiveret…. Firefox vil starte op med vinduet Firefox køres i fejlsikret tilstand.
    Bemærk: Du kan også starte Firefox i fejlsikret tilstand ved at holde tasten Skift nede, mens Firefox startes. holde tasten Alternativ nede, mens Firefox startes. afslutte Firefox og i Terminal starte Firefox med kommandoen firefox -safe-mode
    Du kan være nødt til at angive stien til Firefox-installationen (fx /usr/lib/firefox)
  2. When the Firefox Safe Mode window appears, press the button Continue in Safe ModeStart in Safe Mode.

After Firefox starts in Safe Mode, test for your problem.

Problemet opstår stadig i fejlsikret tilstand

If your problem persists in Safe Mode, it is not being caused by an extension, theme or hardware acceleration. Other possible causes could be plugins or changes made to Firefox preference settings, which are not disabled in Safe Mode.

Problemet opstår ikke i fejlsikret tilstand

If your problem did not occur in Safe Mode, it is most likely because of an extension, theme or hardware acceleration. Continue following the steps in this article to determine the cause of your problem.

Deaktiver hardware acceleration

With some graphics card and graphics driver setups, Firefox may crash or have trouble showing text or objects on pages when using hardware acceleration. You can try turning off hardware acceleration to see if it fixes the problem.

  1. Klik på menuknappen New Fx Menu Fx57Menu , og klik så på Indstillinger.Indstillinger.
  2. Select the Advanced panel and the General tab.
  3. Uncheck Use hardware acceleration when available.
  4. Klik på menuknappen New Fx Menu , og klik så på AfslutAfslut Close 29 .

    Klik på menuknappen Fx57Menu , og klik så på Afslut. Klik på Firefox-menuen øverst på skærmen, og klik så på Afslut Firefox.Klik på menuknappen Fx57Menu , og klik så på Afslut.

  5. Start Firefox the way you normally do.

If the problem is no longer happening, then hardware acceleration was likely the cause. You can try updating your graphics drivers to see if that fixes it or simply run without hardware acceleration. Otherwise, your problem is likely related to extensions or themes. Continue with the steps in this article to see if they help.

Skift til standard temaet

If you are using a theme other than the default Firefox theme:

  1. Klik på menuknappen Fx57menu , klik på Fx57Addons-icon Tilføjelser, og klik så på Appearance.
  2. Select the default theme, then click the Enable button, to make Firefox switch to that theme.
  3. Click Restart Firefox if necessary.

After you restart Firefox, test for your problem. If it no longer occurs, the theme you were using was causing it. If it still occurs, continue following the steps in this article.

Deaktiver alle udvidelser

To determine whether a faulty extension is causing your problem, you can disable all of your installed extensions:

  1. Klik på menuknappen Fx57menu , klik på Fx57Addons-icon Tilføjelser, og klik så på Extensions.
  2. Click the name of an extension in the list to select it.
  3. Click Disable to disable the selected extension.
  4. Repeat this for each of the other extensions in the list.
  5. Click Restart Firefox.

After you restart Firefox, all extensions will be disabled. Test for your problem.

  • If the problem still occurs with all extensions disabled, it is most likely that the localstore.rdf file in your Firefox profile is corrupt. You can reset toolbars and controls to resolve the problem.

If the problem no longer occurs with all extensions disabled, one of your extensions was causing it. To find the extension that was causing your problem, continue as follows:

Find udvidelser med fejl

To determine which of your disabled extensions was causing your problem, you can re-enable each extension one at a time.

  1. Klik på menuknappen Fx57menu , klik på Fx57Addons-icon Tilføjelser, og klik så på Extensions.
  2. Click the name of an extension in the list to select it.
  3. Click Enable to enable the selected extension.
  4. Click Restart Firefox.

After you restart Firefox, test for your problem. If the problem comes back, the extension you just enabled was causing it.

Bemærk: If you have a large number of extensions, it may be quicker to enable more than one extension at a time. The method with the fewest number of restarts required is: Enable half the extensions in this list, then restart Firefox and test for the problem. If the problem reoccurs, you know that the faulty extension is one of the ones you just enabled. If the problem does not occur, you know the faulty extension is one of the disabled ones. Repeat the process until the faulty extension is found.

After you find the extension that was causing your problem, disable or uninstall the faulty extension and re-enable the other extensions in the Add-ons window.

Opdater udvidelser

If an extension was causing your problem, it may have an update available that will fix it:

  1. Klik på menuknappen Fx57menu , klik på Fx57Addons-icon Tilføjelser, og klik så på Extensions.
  2. Click Find Updates.
  3. If updates are found, install them by clicking Install Updates.
  4. When the installation is complete, click Restart Firefox.

After Firefox restarts, your extensions will be updated. If the extension that was causing your problem had an update, re-enable it and test for your problem again.

Kontroller udvidelses indstillinger

Some problems are caused if the settings of an extension override Firefox settings (e.g. problems with toolbars). Therefore you may want to check the extension's settings to see if you can find the option that is causing your problem:

  1. Klik på menuknappen Fx57menu , klik på Fx57Addons-icon Tilføjelser, og klik så på Extensions.
  2. For the extension that is causing your problem click the OptionsPreferences button.
  3. Click your way through the settings to see if there is an option that may solve your problem.
  4. If you found a suitable option, click Save and Restart Firefox.
